本公开实施例的一个有益效果在于，如果本地应用不支持目标文档的原始字体，本地应用使用其支持的第一字体来显示目标文本并且根据原始字体对应的字符测量数据对目标文本进行排版，使得本地应用在缺失原始字体的情况下仍然可以保持 文档排版和原始排版的一致性。

在一个例子中，该本地应用为在终端设备上可以运行的应用，例如可以是原生应用、Web应用、混合应用、轻应用等。原生应用指的是能直接运行于当前操作系统的应用程序。Web应用指需要在浏览器中运行的网页应用。混合应用则可以是原生应用和Web应用的结合，通常是一个原生应用内嵌了浏览器。轻应用是一种不需要下载安装即可使用的应用程序，用户可以即搜即用或者直接扫码使用。
图1所示的文档处理系统仅仅是说明性的并且绝不意味着对本说明书实施例、其应用或使用的任何限制。本领域技术人员应当理解，尽管前面描述了服务器和终端设备的多个装置，但是，本说明书实施例可以仅涉及其中的部分装置。例如，服务器可以只涉及处理器、存储器以及通信装置，终端设备可以只涉及处理器、存储器、通信装置、输入装置、显示屏。本领域技术人员可以根据本说明书实施例所公开的方案设计指令。指令如何控制处理器进行操作，是本领域公知技术，故在此不再详细描述。
参见图2所示，本公开实施例提供了一种文本的排版方法。该方法包括步骤S102-S108。步骤S102-S108可以由终端设备实施。
步骤S102、确定目标文本使用的原始字体。
在本公开实施例中，目标文本可以是文档中的任一部分文本。在一个例子中，终端设备从文档中获取目标文本的原始字体信息，从而确定目标文本使用的原始字体。一般情况，该原始字体信息可以存储在文档的文档数据中。
在本公开实施例中，字体可以包括加载在终端设备的操作系统中的字体、加载在终端设备的客户端(例如浏览器或应用端等)中的字体或服务器中存储的字体，也可以是文档文件中携带的字体。其中，文档文件可以携带字体，但携带字体的文档文件通常具有比较大的数据量。此外，加载在终端设备的操作系统中的字体、加载在终端设备的客户端中的字体和文档文件携带的字体，都属于终端设备的本地应用能够支持的字体，可统称为本地字体。而存储在服务器中的字体，可被称为服务器字体或云字体。
步骤S104、确定本地应用是否支持原始字体。
在确定目标文本使用的原始字体后，检查本地应用支持的全部字体中是否包括该原始字体，如果不包括，则确定本地应用不支持该原始字体。
本地应用支持的字体可以根据其安装的字体包确定。在一个例子中，如果本地应用安装了某种字体的字体包，说明本地应用支持该字体。通常来说，本地应用的基础数据包中会预先安装有多种大众广为使用的字体包并且可以将其中一种字体设置为默认字体，如果用户想要使用一些小众特别的字体，则需要单独下载对应的字体包。例如，如果终端设备的操作系统或本地应用加载有该原始字体、或目标文本中储存有该原始字体，则认为本地应用支持该原始字体，否则本地应用不支持该原始字体。
步骤S106、在本地应用不支持原始字体的情况下，获取原始字体的字符测量数据。
本公开实施例中所指的字符包括文字和符号，符号包括但不限于标点符号、数字符号、数学符号、特殊符号等等，文字包括但不限于汉字、字母等。
本公开实施例中，字体的字符测量数据包括字符的高度和宽度。原始字体的字符测量数据包括原始字体的字符宽度和原始字体的字符高度，是目标文本中的字符在原始字体状态下的宽度和高度。对于同一种字体，在同一字号下，不同的字符的尺寸可能被设计为相同的或者不同的。如果对于同一种字体，在同一字号下，其所有字符并不采用同一种尺寸，则建立该字号下字符和字符的宽度、高度的映射关系。这样，可将该映射关系作为相应字体的字符测量数据，并可根据该映射关系查找出每个字符在相应字号下的宽度和高度。
在一个例子中，字符测量数据还包括字符的升降值。
参见图3(a)和图3(b)所示，对于同一个汉字“早”，两种不同的字体在同一字号下，宽度和高度都是不同的，升降值也是不同的。图3(b)所示的字体的宽度和高度都小于图3(a)的字体。图3(a)所示的字体的升降值为0，即字体相对于基线没有升降。图3(b)所示的字体的升降值为一正值，即该字体相对于基线有上升。如果字体的升降值为一负值，即表示该字体相对于基线有下降。
在一个例子中，字符测量数据还可以包括其他用于描述字符的位置和/或大小的其他特征，在本文不做限定。
在一个例子中，字体的字符测量数据可通过对字符(例如，可具体为字符的图像模型)进行测量获得。例如，预先以某种字体显示目标文本，测量目标文本在该字体下的字符测量数据，从而得到该字体的字符测量数据。
在一个例子中，服务器中可预先存储有各种字体在各字号下的字符测量数据。
在一个例子中，终端设备获取原始字体的字符测量数据，可以是在终端设备的本地缓存中查询原始字体对应的字符测量数据。
在一个例子中，终端设备获取原始字体的字符测量数据，可以是：先在终端设备的本地缓存中查询原始字体的字符测量数据，在本地缓存中查询不到原始字体的字符测量数据的情况下，从服务器处获取原始字体的字符测量数据。在该例子中，终端设备从服务器处获取到原始字体的字符测量数据后，可以将其存储在本地缓存中，以便于下次再需要使用该字体时，可以从本地缓存中直接读取该字体的字符测量数据。
步骤S108、以本地应用支持的第一字体显示目标文本并根据原始字体的字符测量数据对目标文本进行排版。
在一个例子中，终端设备按照目标文本的原字号以第一字体显示目标文本，并根据原始字体的字符测量数据对以第一字体显示的目标文本进行排版。
在以本地应用支持的第一字体显示目标文本之前，该方法还可以包括确认第一字体的步骤。在本公开实施例中，终端设备从本地应用支持的所有字体中选择出与原始字体相匹配的第一字体。下面进行举例说明：
确定第一字体的例子一：从本地应用支持的所有字体中选择出与原始字体相匹配的第一字体，可包括步骤S202-S206。
步骤S202、获取原始字体的替换字体列表。
在一个例子中，对于任一种字体，预先检测其余字体和该字体的匹配度，选取匹配度达到匹配度阈值的字体作为该字体的替换字体。在本公开实施例中，可以根据两种字体的字符测量数据确定两种字体之间的匹配度。对于任一种字体，可根据其替换字体建立替换字体列表，替换字体列表中的替换字体按照匹配度从高到低进行排序。终端设备可以从服务器处获取到每种字体的替换字体列表。
下面以字体A为例，说明如何确定字体B与字体A的匹配度：
计算字体A的字符C的宽度和字体B的字符C的宽度的差值作为第一差值。
计算字体A的字符C的高度和字体B的字符C的高度的差值作为第二差值。其中，字符C可以是单个字符，也可以是多个字符组成的字符串。
在一个例子中，根据第一差值的绝对值确定字体B与字体A的匹配度，其中，第一差值的绝对值越大，字体B与字体A的匹配度越低，第一差值的绝对值越小，字体B与字体A的匹配度越高。
在一个例子中，根据第二差值的绝对值确定字体B与字体A的匹配度，其中，第二差值的绝对值越大，字体B与字体A的匹配度越低，第二差值的绝对值越小，字体B与字体A的匹配度越高。
在一个例子中，计算第一差值的绝对值和第二差值的绝对值的和值，根据该和值确定字体B与字体A的匹配度，其中，该和值越大，字体B与字体A的匹配度越低，该和值越小，字体B与字体A的匹配度越高。
步骤S204、从替换字体列表的替换字体中确定候选字体，候选字体是本地应用支持的字体。
步骤S206、将候选字体中与原始字体的匹配度最高的确定为第一字体。
在该例子中，从替换字体列表的替换字体中筛选出本地应用支持的候选字体，再进一步从本地应用支持的候选字体中选取和原始字体最为匹配的候选字体(例如，在前述按照匹配度从高到低进行排序的替换字体列表中排序最前的候选字体)作为第一字体。
利用替换字体列表中本地应用支持的候选字体来确定第一字体，不需要终端设备进行复杂计算，更为方便快速。
确定第一字体的例子二：从本地应用支持的所有字体中选择出与原始字体相匹配的第一字体，可包括步骤S302-S304。
步骤S302、确定目标文本的字符类型。
字符类型包括第一类型、第二类型。第一类型是指目标文本的字符为汉字等方块字符，不同汉字的宽度、高度是基本上一样的。第二类型是指目标文本的字符中包括字母、罗马字、蒙古文、或阿拉伯文等字符或者是多种语言混合，这些字符的宽度可能是不一致的，高度也可能是不一致的。
步骤S304、根据与目标文本的字符类型相关联的预设规则，从本地应用支持的所有字体中选择出与原始字体相匹配的第一字体。
在该例子中，根据与目标文本的字符类型对应的规则方式来确定第一字体，下面用例子三、例子四、例子五、例子六进行说明。
确定第一字体的例子三：从本地应用支持的所有字体中选择出与原始字体相匹配的第一字体，可包括步骤S402-S406。
步骤S402、获取候选字体的字符测量数据，候选字体是本地应用支持的字体。
步骤S404、确定目标文本的排版方向。
步骤S406、在目标文本的排版方向为横向排版的情况下，将字符宽度与原始字体的字符宽度最接近的候选字体确定为第一字体。在目标文本的排版方向为竖向排版的情况下，将字符高度与原始字体的字符高度最接近的候选字体确定为第一字体。
在目标文本的排版方向为横向排版的情况下，计算目标文本中的字符在原始字体下的字符宽度和候选字体下的字符宽度之间的差值作为第一差值，第一差值的绝对值越小，表明候选字体的字符宽度与原始字体的字符宽度越接近，选取第一差值的绝对值最小的候选字体作为第一字体。
在目标文本的排版方向为竖向排版的情况下，计算目标文本中的字符在原始字体下的字符高度和候选字体下的字符高度之间的差值作为第二差值，第二差值的绝对值越小，表明候选字体的字符高度与原始字体的字符高度越接近，选取第二差值的绝对值最小的候选字体作为第一字体。
例子三适用于目标文本的字符类型为第一类型和/或第二类型的情况。也就是说，在目标文本中仅含有汉字，或者在目标文本中含有字母、罗马字符的情况下，都可以适用例子三的方式确定第一字体。
确定第一字体的例子四：从本地应用支持的所有字体中选择出与原始字体相匹配的第一字体，可包括步骤S502-S508。
步骤S502、获取原始字体的字体属性和候选字体的字体属性，候选字体是本地应用支持的字体。
字体的字体属性是指字体本身具有的固有属性，可以体现该字体的风格。字体的字体属性可包括字体的粗细程度、加黑程度、倾斜程度等中的一种或者多种。
例如，对于字体的粗细程度，按照从粗到细包括“粗”、“常规”、“细”三种属性值。例如，对于字体的加黑程度，包括“有加黑”、“无加黑”两种属性值。例如，对于字体的倾斜程度，包括“有倾斜”、“无倾斜”两种属性值。
例如，对于“宋体”、“华文细黑”、“方正粗黑宋简体”这三种字体，“宋体”的字体属性是：粗细程度为“细”，加黑程度为“无加黑”，倾斜程度为“无倾斜”；“华文细黑”的字体属性是：粗细程度为“细”，加黑程度为“加黑”，倾斜程度为“无倾斜”；“方正粗黑宋简体”的字体属性是：粗细程度为“粗”，加黑程度为“加黑”，倾斜程度为“无倾斜”。
例如，对于“Times New Roman”和“Forte”这两种字体，“Times New Roman”的字体属性是：粗细程度为“细”，加黑程度为“无加黑”，倾斜程度为“无倾斜”；“Forte”的字体属性是：粗细程度为“粗”，加黑程度为“加黑”，倾斜程度为“有倾斜”。
步骤S504、将字体属性与原始字体的字体属性相同的候选字体确定为目标字体，获取目标字体的字符测量数据。
在一个例子中，字体的字体属性仅包括字体的粗细程度，如果候选字体和原始字体均为“粗”，或者均为“常规”，或者均为“细”，则认为该候选字体和原始字体的属性相同。
在一个例子中，字体的字体属性包括字体的粗细程度、加黑程度以及倾斜程度，如果候选字体和原始字体在粗细程度、加黑程度、倾斜程度三个方面的属性值均一致，则认为该候选字体和原始字体的属性相同。
步骤S506、确定目标文本的排版方向。
步骤S508、在目标文本的排版方向为横向排版的情况下，将字符宽度与原始字体的字符宽度最接近的目标字体确定为第一字体。在目标文本的排版方向为竖向排版的情况下，将字符高度与原始字体的字符高度最接近的目标字体确定为第一字体。
步骤S508的实现方式可以类似于前述步骤S406，这里不再详细说明。
例子四适用于目标文本的字符类型为第一类型和/或第二类型的情况。也就是说，在目标文本中仅含有汉字，或者在目标文本中含有字母、罗马字符的情况下，都可以适用例子四的方式确定第一字体。
在该例子中，在全部候选字体中，过滤掉字体属性与原始字体的字体属性不相同的候选字体，保留字体属性与原始字体的字体属性相同的候选字体作为目标字体，并基于原始字体的字符测量数据在目标字体中确认第一字体，使得选取出的第一字体的风格和原始字体的风格基本上是一致的，进而使得利用本地应用支持的第一字体显示的目标文本和原始字体下的目标文本的呈现风格更为近似。
确定第一字体的例子五，根据与目标文本的字符类型相关联的预设规则，从本地应用支持的所有字体中选择出与原始字体相匹配的第一字体，可以是：终端设备将候选字体的字体标识发送给服务器，以供服务器根据原始字体的字体属性和原始字体下的预设字符串的宽度从候选字体中确定第一字体；然后，服务器将第一字体的字体标识下发给终端设备，终端设备从服务器接收第一字体的字体标识。其中， 所述字体标识可为用于标识字体的名称或编号等。
或者，确定第一字体的例子六，根据与目标文本的字符类型相关联的预设规则，从本地应用支持的所有字体中选择出与原始字体相匹配的第一字体，可以是：终端设备从服务器处获取原始字体的字体属性和原始字体下的预设字符串的宽度，根据原始字体的字体属性和原始字体下的预设字符串的宽度从候选字体中确定第一字体。
其中，候选字体是本地应用支持的字体，预设字符串中包括多个不同的预设字符。预设字符串中的预设字符应当是在字符宽度或字符高度方面中的任一个方面具有代表性的字符。例如，选取任一个汉字以及英文中宽度具有代表性的“w”、“z”、“i”组成预设字符串，其中，“w”、“z”、“i”分别代表三种不同宽度的英文字符，该预设字符串可以为“明WwZzIi”。
例子五、六适用于目标文本的字符类型为第二类型的情况。也就是说，在目标文本中包括字母、罗马字、蒙古文、或阿拉伯文等字符或者是多种语言混合的情况下，可以适用例子五、六的方式确定第一字体。例如，在目标文本的字符类型是字母类型或者多语言混合类型(例如，目标文本中同时含有中文内容和英文内容，或者目标文本中同时含有中文内容和日文内容)的情况下，可以适用例子五、六的方式确定第一字体。基于预设字符串的宽度来确定第一字体，可以适合于不同字符的字符宽度不一样的情况，运算量小，更为高效快速。
在一个例子中，候选字体包括本地应用支持的默认字体和非默认字体。本地应用预先设有默认字体，终端设备安装应用时会设置默认字体，用户可以根据个人喜好自行修改默认字体。
根据原始字体的字体属性和原始字体下的预设字符串的宽度从候选字体中确定第一字体，可包括步骤S602-S604。
步骤S602、如果本地应用支持的默认字体和原始字体的字体属性相同、并且默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的近似程度符合预设标准，将默认字体确定为第一字体。否则，执行步骤S604。
在一个例子中，确定默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的近似程度是否符合预设标准，可包括步骤S6022-S6026。
步骤S6022、确定默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度之间的差值作为第四差值。
步骤S6024、确定该第四差值的绝对值与原始字体下的预设字符串的宽度的比值作为第一比值。
步骤S6026、在该第一比值小于等于预设的第一阈值的情况下，确定默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的近似程度符合预设标准。在该第一比值大于预设的第一阈值的情况下，确定默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的近似程度不符合预设标准。
在一个例子中，默认字体下的预设字符串的宽度和高度与原始字体下的预设字符串的宽度和高度的近似程度符合预设的标准，可包括：默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的比值在0.95～1.05之间，即所述第一比值在0～0.05之间。
步骤S604、将与原始字体的字体属性相同的候选字体作为目标字体，从目标字体中确定第一字体。
在步骤S604中，在全部候选字体中(包括默认字体和非默认字体)，选取与原始字体的字体属性相同的候选字体作为目标字体，
在一个例子中，步骤S604、从目标字体中确定第一字体，可以是：将预设字符串的宽度与原始字体下的最接近的目标字体确定为第一字体。
计算预设字符串在原始字体下的宽度和目标字体下的宽度的差值作为第三差值，第三差值的绝对值越小，表明目标字体与原始字体下的预设字符串的宽度越接近，选取第三差值的绝对值最小的目标字体作为第一字体。通过这种方式，可以使得在未排版之前，本地应用呈现给用户的目标文本的排版和目标文本的原始排版比较相似，排版时只需要进行微调即可。
在一个例子中，步骤S604、从目标字体中确定第一字体，可以是：将预设字符串的宽度最小的目标字体确定为第一字体。
选取预设字符串的宽度最小的目标字体作为第一字体，可以尽量避免本地应用以第一字体显示目标文本时出现字符之间出现重叠覆盖的情况，未排版之前也不容易因出现重叠覆盖给用户造成阅读障碍。
在该例子中，考虑到用户的字体使用习惯，优先考虑将默认字体作为替换原始字体的第一字体。并且，如果默认字体和原始字体的字体属性不相同，或者默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的近似程度不符合预设标准，则从与原始字体的字体属性相同的候选字体中确定第一字体。通过这种方式，兼顾了用户的喜好，并且降低了运算量，节省了处理时间。
上述确认第一字体的例子二到例子六中，确定候选字体、目标字体与原始字体的近似程度、匹配程度的实现方式，也可以应用于确定替换字体列表中的替换字体。
步骤S108中，终端设备以本地应用支持的第一字体显示目标文本并根据原始字体的字符测量数据对第一字体显示的目标文本进行排版，可以有多种方式，下面进行举例说明。
排版例子一：首先确定目标文本的排版方向，根据目标文本的排版方向对终端设备以第一字体显示的目标文本进行排版。在目标文本的排版方向为横向排版的情况下，对目标文本的字符进行第一缩放处理以使得目标文本的字符宽度和原始字体的字符宽度一致。在目标文本的排版方向为竖向排版的情况下，对目标文本的字符进行第二缩放处理以使得目标文本的字符高度和原始字体的字符高度一致。
在例子一中，对字符的缩放可以通过调整字号实现。
在一种实施方式中，在步骤S108中，根据原始字体对应的字符测量数据对终端设备显示的目标文本进行排版，可以是：获取第一字体对应的字符测量数据，根据原始字体对应的字符测量数据和第一字体对应的字符测量数据，对终端设备显示的目标文本进行排版。
排版例子二：首先确定目标文本的排版方向，根据目标文本的排版方向对终端设备以第一字体显示的目标文本进行排版。在目标文本的排版方向为横向排版的情况下，确定第一差值，第一差值为原始字体的字符宽度和第一字体的字符宽度的差值。在第一差值为正值的情况下，调整目标文本的字符的横坐标值。在第一差值为负值的情况下，对目标文本的字符进行缩小处理。在目标文本的排版方向为竖向排版的情况下，确定第二差值，第二差值为原始字体的字符高度和第一字体的字符高度的差值。在第二差值为正值的情况下，调整目标文本的字符的纵坐标值。在第二差值为负值的情况下，对目标文本的字符进行缩小处理。
在该例子中，对字符的缩小处理可以通过调整字号实现。
下面以目标文本的排版方向为横向排版为例进行说明：
参见图3(a)所示，在原始字体下每个字符的字符宽度约为W1。参见图3(b)所示，在第一字体下每个字符的字符宽度约为W2。计算W1与W2的差值DW(＝W1-W2)作为第一差值。
如果该第一差值DW为正值，说明第一字体的字符宽度小于原始字体的字符宽度，则需要调整第一字体下目标文本的每个字符的横坐标的坐标值。
参见图4所示，目标文本是一行内容，包括“早上好今天的天气真好”这10个 字符。在原始字体下，10个字符的横坐标的坐标值为X 1,X 2,…,X 10，排版后，10个字符的横坐标的坐标值为X 1’,X 2’,…,X 10’，则：
X 1’＝X 1+0.5*DW，
X 2’＝X 2+(2-1)*DW+0.5*DW，
…
X n’＝X n+(n-1)*DW+0.5*DW，
…
X 10’＝X 10+(10-1)*DW+0.5*DW，
其中，n为整数，1≤n≤10。
可以看出，调整第一字体下这一行内容中的每个字符的横坐标的坐标值相当于调整这一行内容中的相邻字符之间的间距。
如果该第一差值DW为负值，说明第一字体的字符的宽度大于原始字体的字符的宽度，如果通过调整坐标值，则可能会造成字符之间的重叠，因此，需要缩小终端设备以第一字体显示的目标文本的字号。在一个例子中，根据W1/W2的比值缩小终端设备以第一字体显示的目标文本的字号，并保持第一字体下原来的目标文本的位置(坐标值)不变。例如，W1/W2＝R1，假设这段内容的原始字号为U1，则将这段内容的字号调整为U2，U2＝R1*U1。本文中所述字号为点数制，是本领域技术人员周知的印刷字体的计量方法，例如5磅、12磅等。
下面以目标文本的排版方向为竖向排版为例进行说明：
参见图3(a)所示，在原始字体下每个字符的字符高度均为H1。参见图3(b)所示，在第一字体下每个字符的字符高度均为H2。计算H1与H2的差值DH(＝H1-H2)作为第二差值。
如果该第二差值DH为正值，说明第一字体的字符高度小于原始字体的字符高度，则调整第一字体下每个字符的纵坐标的坐标值。
假设原始字体下的目标文本一共有M行内容，每一行内的字符的纵坐标值是一样的，第1行到第M行的字符的纵坐标值分别为Y 1,Y 2,…,Y M，在排版后，第1行到第M行的字符的纵坐标值分别为Y 1’,Y 2’,…,Y M’，则：
Y 1’＝Y 1+0.5*DH，
Y 2’＝Y 2+(2-1)*DH+0.5*DH，
…
Y m’＝Y m+(m-1)*DH+0.5*DH，
…
Y M’＝Y M+(M-1)*DH+0.5*DH，
其中，m为整数，1≤m≤M。
可以看出，调整第一字体下目标文本的每个字符的纵坐标的坐标值相当于调整目标文本的相邻行之间的行间距。
如果该第二差值DH为负值，说明第一字体的字符的高度大于原始字体的字符的高度，如果通过调整坐标值，则可能会造成字符之间的重叠，因此，需要缩小终端设备以第一字体显示的目标文本的字号。在一个例子中，根据H1/H2的比值缩小终端设备以第一字体显示的目标文本的字号，并保持第一字体下原来的目标文本的位置(坐标值)不变。例如，H1/H2＝R2，假设目标文本的原始字号为U1，则将字号调整为U2，U2＝R2*U1。
排版例子三：首先确定目标文本的排版方向，根据目标文本的排版方向对终端设备以第一字体显示的目标文本进行排版。在目标文本的排版方向为横向排版的情况下，将目标文本的字号调整为第一字号，第一字号是字符宽度与原始字体的字符宽度最接近的字号；确定第一差值，第一差值为原始字体的字符宽度和第一字体的 字符宽度的差值；在第一差值为正值的情况下，调整目标文本的字符的横坐标值；在第一差值为负值的情况下，对目标文本的字符进行缩小处理。在目标文本的排版方向为竖向排版的情况下，将目标文本的字号调整为第二字号，第二字号是字符高度与原始字体的字符高度最接近的字号；确定第二差值，第二差值为原始字体的字符高度和第一字体的字符高度的差值；在第二差值为正值的情况下，调整目标文本的字符的纵坐标值；在第二差值为负值的情况下，对目标文本的字符进行缩小处理。
也就是说，在目标文本的排版方向为横向排版的情况下，终端设备在将第一字体下的目标文本的字号调整为第一字号后，如果字符宽度仍然大于原始字体下的字符宽度，则下调一个字号以使得字符缩小，避免出现字符之间互相覆盖的情况。
类似地，在目标文本的排版方向为竖向排版的情况下，终端设备在将第一字体下的目标文本的字号调整为第二字号后，如果字符高度仍然大于原始字体下的字符高度，则下调一个字号以使得字符缩小，避免出现字符之间互相覆盖的情况。
在该例子中，对字符的缩小处理可以通过调整字号实现。
终端设备对显示的目标文本进行排版后，其显示的目标文本的排版情况和以原始字体显示的目标文本的排版情况更为接近。参见图4所示，对于目标文本“早上好今天的天气真好”，原始字体下和第一字体下进行对比，原始字体下的这段内容的总宽度更宽。经过步骤S108的排版，终端设备使用第一字体显示的这段内容的总宽度和原始字体下的这段内容的总宽度更为接近。通过这种方式，可以保证原始字体下的同一行内容，不会因为改为使用第一字体进行显示而分行。
排版例子四：根据原始字体的字符测量数据对目标文本进行排版，可以包括步骤S1085-S1087。
步骤S1085、将目标文本切分成词。
步骤S1086、累加词中的每个字符在第一字体下的宽度与在原始字体下的宽度的差值，得到调节量。
步骤S1087、计算调节量与词中的字符间隙数量的比值作为第二比值，根据该第二比值调节词中的字符的间隙以使得词中的字符的间隙相同。
例如，目标文本的一个词中一共有T个字符，字符间隙数量为G个，G＝T-1。其中，T个字符中每个字符在第一字体下的宽度与在原始字体下的宽度的差值依次为O 1,O 2,…,O T，累加O 1,O 2,…,O T得到调节量，计算调节量和字符间隙数量的第二比值。如果该第二比值为正值，说明调节量为正值并应该缩小词中字符的间隙，则将词中的字符的间隙减去该第二比值。如果该第二比值为负值，说明调节量为负值并应该增大词中字符的间隙，则将词中的字符的间隙减去该第二比值、也即加上该第二比值的绝对值。
通过这种方式，可以使得同一个词中字符的间隙相同，显示更为均匀。可以适用于第二类型的目标文本，在不同字符的宽度不相同的情况下，仍可以使得同一个词中的字符显示的更加均匀。排版例子四可以在前述任一排版例子之后进行。
在一个例子中，本地应用先对目标文本的字符的宽、高进行排版，然后按照原始字体对应的字符升降值调整目标文本的字符的升降值。
本公开实施例的一个有益效果在于，如果终端设备的本地应用不支持目标文本的原始字体，本地应用使用其支持的第一字体来显示目标文本并且根据原始字体的字符测量数据对目标文本进行排版，使得本地应用在缺失原始字体的情况下仍然可以保持文档排版和原始排版的一致性。
参见图5所示，本公开实施例提供了一种文本的排版方法。该方法包括步骤S702-S706。步骤S702-S706可以由服务器实施。
步骤S702、接收终端设备发送的目标文本的原始字体的字体标识。
步骤S704、根据原始字体的字体标识查询出原始字体的字符测量数据。
步骤S706、将原始字体的字符测量数据发送给终端设备，以供终端设备根据原始字体的字符测量数据对以其本地应用支持的第一字体显示的目标文本进行排版。
在一个例子中，服务器中预先存储有各种字体的字体属性、以及各种字体在各字号下的字符测量数据。字体的字符测量数据可包括字符的高度和宽度。字体的字符测量数据还可以包括字符的升降值。字体的字体属性是指字体本身具有的固有属性，可以体现该字体的风格。字体的字体属性可包括字体的粗细程度、加黑程度、倾斜程度的一种或者多种。
在一个例子中，在终端设备以其本地应用支持的第一字体显示目标文本之前，该方法还包括：根据原始字体的字体标识获取原始字体的替换字体列表。从替换字体列表的替换字体中确定候选字体，候选字体是终端设备的本地应用支持的字体。将在替换字体列表中与原始字体最匹配的候选字体确定为第一字体。将第一字体的标识发送给终端设备。
在一个例子中，在终端设备以其本地应用支持的第一字体显示目标文本之前，该方法还包括：将原始字体的字体属性和原始字体下的预设字符串的宽度发送给终端设备，以供终端设备根据原始字体的字体属性和原始字体下的预设字符串的宽度从候选字体中确定第一字体。其中，候选字体是终端设备的本地应用支持的字体，预设字符串中包括多个不同的预设字符。
在一个例子中，在终端设备以其本地应用支持的第一字体显示目标文本之前，该方法还包括：根据原始字体的字体属性和原始字体下的预设字符串的宽度从候选字体中确定第一字体，将第一字体的字体标识发送给终端设备。其中，候选字体是终端设备的本地应用支持的字体，预设字符串中包括多个不同的预设字符。
在一个例子中，候选字体包括本地应用支持的默认字体和非默认字体。
在一个例子中，根据原始字体的字体属性和原始字体下的预设字符串的宽度从候选字体中确定第一字体，包括：如果默认字体和原始字体的字体属性相同、并且默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的近似程度符合预设标准，将默认字体确定为第一字体。否则，将与原始字体的字体属性相同的候选字体作为目标字体，并从目标字体中确定第一字体。
在一个例子中，确定默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的近似程度是否符合预设标准，包括：确定默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的差值作为第四差值。确定所述第四差值的绝对值与原始字体下的预设字符串的宽度的比值作为第一比值。在所述第一比值小于等于预设的第一阈值的情况下，确定默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的近似程度符合预设标准。在所述第一比值大于预设的第一阈值的情况下，确定默认字体下的预设字符串的宽度与原始字体下的预设字符串的宽度的近似程度不符合预设标准。
在一个例子中，从目标字体中确定第一字体，包括：将预设字符串的宽度与原始字体下的最接近的目标字体确定为第一字体；或者，将预设字符串的宽度最小的目标字体确定为第一字体。
本公开实施例的一个有益效果在于，如果终端设备的本地应用不支持目标文本的原始字体，服务器将原始字体的字符测量数据提供给终端设备，以使得终端设备能够根据原始字体对应的字符测量数据对以本地应用支持的第一字体显示的目标文本进行排版，进而使得本地应用在缺失原始字体的情况下仍然可以保持文档排版和原始排版的一致性。
