我想在我的 tex 文档中使用 ASCII 字符输入带有多音调重音的希腊字母（古希腊语）（这样我就不需要更改键盘布局）。我正在使用 polyglossia。
我一直遵循这里顶部答案中列出的方法：
Stackexchange：如何使用“ascii 键盘”和 XeTeX、Polyglossia 插入希腊语
我创建了一个映射文件 asciitogreek.map 并将其放在与 tex 文件相同的目录中：
; TECkit mapping for ASCII Greek <-> Unicode characters

RHSName "UNICODE"
pass(Unicode)
; Class "letter" consists of letters and characters denoting accents
; in order to cope with "sigma finalis", i.e., A-Z a-z ` ' > < ~
; we don't need the double quote because it goes only after a vowel

然后我运行了以下命令：
teckit_compile asciitogreek.map
并创建了最小工作示例 tex 文件来向您展示问题：
\documentclass{scrreprt}
%\usepackage[cm-default]{fontspec}
%\setmainfont{Liberation Serif}
%\setromanfont{Liberation Serif}
%\usepackage{xunicode}
%\usepackage{fixltx2e}
\usepackage{polyglossia}
\setdefaultlanguage[spelling=new,latesthyphen=true]{german}
\setotherlanguage[variant=ancient]{greek}
\newfontfamily{\greekfont}[Mapping=asciitogreek]{FreeSerif}
\newfontfamily{\greekfontsf}[Mapping=asciitogreek]{FreeSans}
\newfontfamily{\greekfonttt}[Mapping=asciitogreek]{FreeMono}
\newcommand{\gk}[1]{\textgreek[variant=ancient]{#1}}
\begin{document}
\gk{d~wr>'a}
\gk{δῶρα}
\end{document}
编译工作正常。但是，w 之前的 ~ 未显示在文档中。相反，有一个小间隙。这显然不是字体问题，因为直接输入 unicode 键就可以了，如第二个示例所示。
请参阅 pdf 中的屏幕截图：
但是，我检查了映射，其中的 unicode 键似乎是正确的。虽然映射可能出了问题。将希腊语变体从“古”改为“多音调”也无济于事。
如果有必要的话，我在 kubuntu 14.04 trusty (LTS) 上使用 texlive 2013.20140215-1。
有人有什么好主意吗？
答案1
您还需要更改类别代码~：
\newcommand{\gk}{\begingroup\catcode`~=12 \dogk}
\newcommand{\dogk}[1]{\textgreek[variant=ancient]{#1}\endgroup}
另一种可能性是利用~活动的事实，并在本地将其定义为~具有正确类别代码的。
\documentclass{scrreprt}
\usepackage{fontspec}
\usepackage{polyglossia}
\setdefaultlanguage[spelling=new,latesthyphen=true]{german}
\setotherlanguage[variant=ancient]{greek}
\newfontfamily{\greekfont}[Mapping=asciitogreek]{FreeSerif}
\newfontfamily{\greekfontsf}[Mapping=asciitogreek]{FreeSans}
\newfontfamily{\greekfonttt}[Mapping=asciitogreek]{FreeMono}
\begingroup\lccode`?=`~
\lowercase{\endgroup\def\gktilde{\def~{?}}}
\protected\def\gk{\begingroup\gktilde\dogk}
\newcommand{\dogk}[1]{\textgreek[variant=ancient]{#1}\endgroup}
\begin{document}
\tableofcontents
\section{Section \gk{d~wr>'a}}
\gk{d~wr>'a}
\gk{δῶρα}
\end{document}
