Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character code conversion apparatus and a recording medium required between systems having different character code systems, wherein a conversion error occurs in a predetermined code conversion table to an arbitrary character code. The present invention relates to a character code conversion device having a correction function for conversion.

[0002]

2. Description of the Related Art Heretofore, when a character code conversion device finds an undefined character code in a code conversion table, the character code conversion device outputs a substitute character or interrupts the conversion process.

[0003] Most of the characters that cause a conversion error are undefined characters in the code conversion table for user-defined characters and non-JIS-standard extended characters, and usually need to be converted to arbitrary characters in the conversion destination system. is there.

For this reason, according to the configuration shown in FIG. 10, the user investigates a character causing a conversion error before executing the conversion process, and corrects the input data or the code conversion table in advance. To investigate the existence of undefined characters, it is necessary to create or execute a manual or investigation program.

FIG. 10 is an explanatory diagram of the prior art. FIG.
At 0, the input data 41 is the data of the character code to be converted.

[0006] The survey program 42 is composed of input data 41
This is a program that checks whether a character code that causes a conversion error is included in it. The investigation result list 43 is a list of character codes that cause a conversion error when the input data 41 is read by the investigation program 42, and a result of an examination of the position.

[0007] The table correction 44 is a search result list 43.
, The code conversion table 45 is corrected for the character code in which the conversion error has occurred. The code conversion table 45 is a table for converting input data.

[0008] The character code conversion device 46 receives the input data 4
1 is converted into a conversion destination code using the corrected code conversion table 45 and stored as output data 47.

The output data 47 is character code data after conversion. Next, the operation will be briefly described. (1) The investigation program 42 examines the character code causing the conversion error and the position of the input data 41 with reference to the code conversion table 45, and outputs the investigation result list 43.

(2) The table correction 44 corrects the code conversion table 45 based on the investigation result list 43, such as registering the character code of the conversion destination for the character code causing the conversion error.

(3) The character code converter 46 converts the input data 41 into the character code of the conversion destination using the corrected code conversion table 45 and stores it as output data 47.

[0012]

As described above, there is a problem that the search for an undefined character is very troublesome and inefficient. In addition, since the search program searches for conversion error characters from the entire input data, if the amount of data is large, it is necessary to check, convert, and read twice.
There was also a problem that processing time was required.

[0013] The present invention solves these problems.
The input data is converted with reference to the code conversion table.If the code is undefined, it is output as a substitute character, the character code and position are stored in the table, and replaced with the specified character code based on the table. The object is to reflect the data in the code conversion table, to quickly realize the character code conversion by reading the character data once, and to automatically reflect the character code in the next and subsequent code conversions.

[0014]

Means for solving the problem will be described with reference to FIG. In FIG. 1, a character code conversion means 2 converts a character code in input data 1 with reference to a code conversion table 4.

The conversion error storage means 3 replaces the substitute character code in the case of a conversion error and stores the original character code and its position information in the conversion error history table 5.

The output data 6 is a converted character code. The conversion error correction means 7 is for displaying the contents of the conversion error history table 5 on the display / input device 8 and replacing (correcting) a substitute character with a correct character in response to an error action input.

The error handling reuse unit 9 reflects the replacement character in the code conversion table 4 when the replacement character is replaced with a correct character (registers the correct character code in association with the original character code).

Next, the operation will be described. The character code conversion unit 2 converts the character code extracted from the input data 1 to another character code with reference to the code conversion table 4 and outputs the converted character code. The conversion error accumulation unit 3 has a conversion error due to an undefined code. Sometimes, the substitute code is output, the original character code, and the output position are stored in the conversion error history table 5, and the conversion error correction means 7 displays the converted character code and the substitute character, and stores the converted character code in the conversion error history table 5. The stored original character code and output position information are displayed.

At this time, in response to the input of the character code output by the conversion error correction means 7 for the original character code displayed on the display / input device 8, the substitute character is replaced with the character of the character code. I have to.

Further, when the conversion error correction means 7 inputs a character to be output with respect to the original character code displayed on the display / input device 8, the substitute character is replaced with the character.

Further, the error treatment reusing means 9 registers the character code of the character obtained by replacing the substitute character in the code conversion table 4 in association with the original character code, and uses it in the next and subsequent times.

Therefore, the input data 1 is converted with reference to the code conversion table 4, and in the case of an undefined code, it is output as a substitute character and the character code and position are stored in the conversion error history table 5, and the conversion error is stored. By replacing the character code or character with the designated character code based on the history table 5 and reflecting the result in the code conversion table 4, the character code can be quickly converted by one reading of the character data, and the next and subsequent processes can be performed. It can be automatically reflected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment and operation of the present invention will be sequentially described in detail with reference to FIGS. Here, the program read from the recording medium or the program read from the hard disk device as the external storage device, or the program read from the external storage device of the center and transferred via the line is loaded into the main storage and activated. , The following various processes are performed.

Here, the operation of the configuration of FIG. 1 will be described with reference to FIG. 2 and FIG. FIG. 2 is a diagram (part 1) for explaining the operation of the present invention. (1) The character code conversion means 2 reads the input data 1 as in S1, refers to the code conversion table 4, converts the character code, and outputs it as output data 6 as shown in S4.

(2) If there is an undefined code in the read input data 1 during the conversion of the character code in (1), the conversion error storage means 3 shows the undefined code in the conversion error history table 5. In this way, the information on the code value, the number of occurrences, and the output position (line-column) is accumulated, and the substitute character (substitute character code) is output as the output data 6.

According to the above (1) and (2), as shown in the figure, as the output data 6, characters (character codes) after code conversion and undefined codes are output as alternative characters (alternative character codes) and output. In the conversion error history table 5, information on the code value of the original character of the substitute character (substitute character code), the number of occurrences, and the output position (line-digit) is accumulated.

FIG. 3 is a diagram (part 2) for explaining the operation of the present invention. (3) Based on the conversion error history table 5 stored in (2), the conversion source code, the number of occurrences, and the conversion destination code are displayed on the display / input device 8 as shown in FIG. And prompts for the input of the conversion destination code (S11, S12).

(4) In response to the prompting of the input of the conversion destination code in (3), when the operator key-inputs the converted character code into the column of the conversion destination code on the display / input device 8, a conversion error occurs. As shown in S13, the correcting means 7 creates a new association table in which the conversion source code and the conversion destination code are associated with each other, and substitutes the substitute character in the output data based on the new association table. It is replaced with a character, as shown in the output data 6 shown.

With regard to the substitute characters in the output data 6 by the above (3) and (4), the fields of the conversion source code, the number of occurrences, and the conversion destination code stored in the conversion error history table 5 are displayed and input by the display / input device 8. It is possible to automatically replace the substitute character in the output data 6 with the character of the conversion destination code in response to the input of the conversion destination code displayed above.

Next, in accordance with the order shown in the flow chart of FIG. 4, the alternative character is output to the output data 6 having the configuration of FIG. 1, and the code value of the conversion source, the number of occurrences, and the output position are registered in the conversion error history table 5. Will be described in detail.

FIG. 4 is a flowchart (part 1) for explaining the operation of the present invention. In FIG. 4, S21 reads input data. This reads input data 1 as shown in S1 of FIG. 2 described above.

In step S22, characters are extracted one by one. S23
Is searched from the code conversion table. That is, the code conversion table 4 is searched, and a character code of a conversion destination with respect to a character code of a conversion source is searched.

At S24, it is determined whether the code conversion table 4 exists. In the case of YES, the data is converted in S30 and output as output data 6, and the process proceeds to S31. On the other hand, in the case of NO, it is determined that the code is an undefined code.
9 is executed.

In S25, the conversion error history table 5 is searched. In this case, the conversion error history table 5 of FIG. 2 described above is searched to determine whether the same undefined code has been registered before. In the case of YES, it is determined that the conversion error history table 5 has already been registered.
Updates the number of occurrences of the entry of the corresponding code value in the conversion error history table 5, adds the output position (line-digit),
Go to 29. On the other hand, in the case of NO in S25, it is determined that the conversion error has not been registered in the conversion error history table 5, so that
In S28, a new registration is made in the conversion error history table 5, and the original code (code value), the number of occurrences, and the output position (line-digit) are registered, and the process proceeds to S29.

In step S29, the data is output as a substitute character. this is,
As shown in the output data 6 of FIG. 2 described above, an alternative character (here, @) is output for an undefined code. S3
1 determines whether the input data is finished. In the case of YES, the processing has been completed for all the input data 1, so that
End (END). In the case of NO, the process returns to S22 and the next one character is taken out and repeated.

As described above, the input data 1 is read, and code conversion is performed one character at a time with reference to the code conversion table 4. When an undefined code appears at this time, the code value and the number of occurrences are stored in the conversion error history table 5. By registering the output position (line-column) and outputting the substitute character, even if there is an undefined code, the output data 6 is output with the substitute character, and the code value of the conversion source, the number of occurrences, and the output position are set. This can be stored in the conversion error history table 5.

Next, in accordance with the order shown in the flowchart of FIG. 5, the substitute character in the output data 6 is changed to the correct character (character code) based on the conversion error history table 5 having the configuration of FIG.
The procedure for substituting into is described in detail.

FIG. 5 is a flowchart (part 2) for explaining the operation of the present invention. In FIG. 5, S41 requests correction. In this case, a correction request for converting a substitute character (substitute character code) in the output data 6 described above into a correct conversion destination character (character code) is issued.

In step S42, the conversion error history table 5 is read. In step S43, a list is displayed. In this case, as shown in the screen of FIG. 8, which will be described later, the output data 6 (alternative character is @) is displayed in the left window 2 and the contents of the conversion error history table 5 are displayed in the right window 1.

In step S44, a selection is made. In step S45, a conversion destination code is input. In these steps S44 and S45, the operator selects any entry on the error list in the window 1 on the right side of FIG. 8 displayed in S43, for example, and key-inputs the correct code of the conversion destination.

A step S46 checks whether the operator is correct. If OK, proceed to S47. In the case of NG,
It returns to S44 and repeats. In step S47, the conversion error history table 5 is updated. This updates the correct conversion destination code input by the operator in the conversion error history table 5 of FIG. 3 described above.

In step S48, it is determined whether the correction request has been completed.
In the case of YES, the process proceeds to S49. If NO, S
Return to step 42 and repeat. In step S49, a replacement request is made. Since the conversion error history table 5 is updated, it is requested that the conversion error history table 5 be collectively replaced with a correct character (character code) for the substitute character in the output data 6.

In step S50, the conversion error history table 5 is read. In step S51, the output positions are sequentially extracted. S52
Replaces the substitute character in the output data 6 with the conversion destination code based on the output position.

A step S53 decides whether or not the history is over. YE
In the case of S, the process ends (END). In the case of NO,
It returns to S51 and repeats. As described above, the output data 6 including the substitute character and the contents of the conversion error history table 5 are displayed as shown in windows 2 and 1 of FIG. Is selected and the correct code of the conversion destination is input, it is possible to automatically replace the corresponding substitute character in the output data 6 with the correct conversion destination character (character code).

Next, according to the order shown in the flow chart of FIG. 6, the procedure for replacing the substitute character in the output data 6 with a correct character based on the conversion error history table 5 having the structure of FIG. 1 will be described in detail. .

FIG. 6 is a flowchart (part 3) for explaining the operation of the present invention. In FIG. 5, S61 requests correction. In this case, a correction request for converting the substitute character in the output data 6 described above into a correct conversion destination character is issued.

In step S62, the conversion error history table 5 is read. In step S63, an error list is displayed on the window 1. This displays an error list of the conversion error history table 5 in a window 1 on the right side of the screen of FIG.

In step S64, the output data is read. S65
Displays output data in window 2. This displays the output data 6 (alternative character is ■) in the left window 2 on the screen of FIG. 9 described later.

In step S66, the substitute character on the window 2 is highlighted from the output position of the conversion error history table 5,
Position as the first alternative character. S67 is the window 2
In, enter the correct destination character instead of the substitute character. In these steps S66 and S67, as shown in FIG. 9 described later, the substitute character (represented by ■) in the output data 6 on the left window 2 is highlighted, and as shown in the lower right error correction input of FIG.・ Position: ・ Conversion source code: ・ Conversion destination code: Input the correct character after conversion in the conversion destination code field of (). May be).

A step S68 decides whether there is another same conversion source code. This is in response to the input of the correct converted character in S67, and it is determined whether there is another same conversion source code. If YES, all the same conversion source codes in the output data 6 on the window 2 are replaced with correct conversion characters in S69, and the process proceeds to S70. On the other hand, if NO in S68, the process proceeds to S70.

In step S70, the input conversion destination character is reflected on the conversion destination code of window 1. S71 positions the next alternative character on the window 2. A step S72 decides whether or not the alternative character ends. In the case of YES, the process proceeds to S73. If NO, the process returns to S67 and repeats.

At S73, confirmation is made. If OK, S
Proceed to 74. If NG, return to S66 and repeat.
A step S74 updates the output data.

In step S75, the conversion error history table 5 is updated. As described above, the output data 6 including the substitute character
9 and the contents of the conversion error history table 5 which will be described later.
When the correct character of the conversion destination is input in the window 2 (or in the error correction input window at the lower right), the corresponding substitute character in the output data 6 is automatically displayed. It is possible to replace the character with a correct conversion destination character (character code).

Next, a procedure for reflecting the contents of the conversion error history table 5 having the configuration shown in FIG. 1 on the code conversion table 4 will be described in detail in accordance with the order shown in the flowchart of FIG.

FIG. 7 is a diagram (part 4) for explaining the operation of the present invention. FIG. 7A shows a flowchart. In FIG. 7A, S81 requests reuse.

A step S82 reads the conversion error history table. In step S83, the conversion destination codes are sequentially extracted. S84
Performs addition to the code conversion table 4. The addition is performed by adding the conversion source code: the conversion destination code: to the code conversion table 4.

A step S85 decides whether or not the history is over. YE
In the case of S, the process ends (END). In the case of NO,
It returns to S83 and repeats. As described above, the undefined conversion destination code registered in the conversion error history table 5 can be added to the code conversion table 4 as a pair of the conversion source code and the correct conversion destination code.

FIG. 7B shows a state in which the data is added to the code conversion table 4. Here, the new association table of FIG. 3 described above is created from the conversion error history table 5, and
The conversion source code and the correct conversion destination code are paired and added to the code conversion table 4.

As described above, the undefined code is automatically added to the code conversion table 4, and the code is automatically converted from the next time. FIG. 8 shows a display example (part 1) of the present invention. This displays the output data 6 in the window 2 on the left side (alternative characters are indicated by ■),
The right window 1 displays the contents of the conversion error history table 5 (conversion source code, conversion destination code, number of occurrences, output position). Here, when the operator inputs the conversion destination code by a key, it is automatically registered as the conversion destination code, and the corresponding substitute character in the output data 6 is automatically replaced with the character corresponding to the correct conversion destination code and displayed. .

FIG. 9 shows a display example (part 2) of the present invention. This means that the output data 6 is displayed in the left window 2 (alternative characters are indicated by ■), and the contents of the conversion error history table 5 (conversion source code, conversion destination code, number of occurrences, output position) are displayed in the right window 1 Are displayed, and correct characters are input (and character codes are displayed together) as an output position, a conversion source code, and a conversion destination code in an error correction input window at the lower right. Here, when the operator inputs the character of the conversion destination by a key, it is automatically registered as a conversion destination code, and the corresponding substitute character in the output data 6 is automatically replaced with a correct character (conversion destination code) and displayed. .

The conversion of the character code according to the present invention is as follows.
As described above, in addition to the input of the correct character code for the undefined character code and the real-time operation, the position information for the undefined character code is stored, and batch processing is performed simultaneously with the input of the correct character code. Needless to say, this may be done.

[0062]

As described above, according to the present invention,
The input data 1 is converted with reference to the code conversion table 4. If the code is an undefined code, it is output as a substitute character, and the character code and position are stored in the conversion error history table 5. The character code or the character designated by the above is replaced and reflected in the code conversion table 4, so that the character code can be quickly converted by one reading of the character data, and at the next time. Can be automatically reflected in the process. This eliminates the need to check for undefined codes beforehand in advance, and provides a high-quality undefined character search function by code conversion. Can be automatically added to the code conversion table 4 from the next time.

Further, when editing an undefined character code, the character string before and after it is displayed, so that the character string to be edited can be easily estimated from the context. Therefore, the user does not need to refer to the file before the change one by one.

In correcting an undefined character code,
Since the undefined character, that is, the character to be corrected is sequentially searched, and a screen for prompting the correction is displayed, the user does not need to search for the character to be edited, and the user's work load is reduced.
