当拉丁语设为主要语言时，带有 \XeTeXinterchartoks 的自定义字距调整对无法与 Polyglossia 配合使用

Question

我的尝试：为拉丁语创建（通常缺失的）自定义字距对“QV”。

我的期望是：自定义字距调整对能够适用于所有语言。

polyglossia我得到的结果是：启用拉丁语言时，字距根本不改变。

任何想法如何解决这一问题？

梅威瑟：

\documentclass{article}

% Set language to Latin.
\usepackage{polyglossia}
%\setdefaultlanguage{french} % Works for German, English, French etc.
\setdefaultlanguage{latin} % DOES NOT work for Latin.

\XeTeXinterchartokenstate = 1
\newXeTeXintercharclass \mycharclassq
\XeTeXcharclass `\Q \mycharclassq
\newXeTeXintercharclass \mycharclassv
\XeTeXcharclass `\V \mycharclassv
\XeTeXinterchartoks\mycharclassq\mycharclassv={\kern-4pt } % Exaggerated for this example.

Answer 1

latin除非调用模块，否则polyglossia设置\XeTeXinterchartokenstate为 0 variant=ecclesiastic，因为 interchar 功能用于更改标点符号间距。

您可以在输入拉丁语时将状态设置为 1。

\documentclass{article}

% Set language to Latin.
\usepackage{polyglossia}
\setdefaultlanguage{latin}

\XeTeXinterchartokenstate = 1
\newXeTeXintercharclass \mycharclassq
\XeTeXcharclass `\Q \mycharclassq
\newXeTeXintercharclass \mycharclassv
\XeTeXcharclass `\V \mycharclassv
\XeTeXinterchartoks\mycharclassq\mycharclassv={\kern-4pt } % Exaggerated for this example.

\makeatletter
\gappto\blockextras@latin{\XeTeXinterchartokenstate = 1 }
\gappto\inlineextras@latin{\XeTeXinterchartokenstate = 1 }
\makeatother
