我想从 TeX 源制作一个外观整洁的 PDF 文档。TeX 文件主要是 ASCII 文本，带有少量非 ASCII 符号（方案中的箭头、标记列表项的自定义项目符号、致谢部分贡献者姓名中的象形文字等）。
反过来，TeX 源是由 Sphinx 根据第一个源构建的。
非 ASCII 符号不会打印在输出 PDF 中，因为整个文档默认使用的字体中没有它们的字形。
因此，我编写了一个 shell 脚本，扫描 TeX Live 安装目录中的 .pfb、.otf 和 .ttf 文件，并为找到的每种字体创建如下 TeX 文档：
\documentclass{article}
\usepackage[english]{babel}
\usepackage{fontspec}
\usepackage{multido}
\font\testedfont="[/usr/share/texlive/texmf-dist/fonts/type1/wadalab/dgj/dgjkj.pfb]"
\font\basictextfont="cmr10"
\title{Find glyph for Unicode 80A5 in dgjkj.pfb}
\begin{document}
\newcounter{glyphslotnum}
\newcommand\findglyphslotnum{}
\newcounter{totalglyphnum}
\newcommand\findtotalglyphnum{}
Test glyphs
{\basictextfont{Font filename: dgjkj.pfb}}
\testedfont
\renewcommand\findglyphslotnum{\the\XeTeXcharglyph"80A5}
\setcounter{glyphslotnum}{\findglyphslotnum}
\renewcommand\findtotalglyphnum{\the\XeTeXcountglyphs\testedfont}
\setcounter{totalglyphnum}{\findtotalglyphnum}
%\multido{\i=0+1}{\value{totalglyphnum}\relax}{
%{\basictextfont\i:\,}{\testedfont\XeTeXglyph\i}
%}
\basictextfont
dgjkj.pfb: total \number\value{totalglyphnum} glyphs
\ifnum\value{glyphslotnum}>0{\message{Glyph for 80A5 exists in dgjkj.pfb (slot \number\value{glyphslotnum})}Glyph for Unicode 80A5 exists in dgjkj.pfb at slot \number\value{glyphslotnum}.
It looks like [{\testedfont\XeTeXglyph\value{glyphslotnum}}] (by $\backslash$XeTeXglyph)
or [{\testedfont{\char"80A5}}] (by $\backslash$char)
or [{\testedfont{\symbol{"80A5}}}] (by $\backslash$symbol)
}\fi
\end{document}
它给出如下输出（复制此处：dgjkj.pfb_U80A5.jpg)：
取消注释多重循环将提供字体中所有字形的列表。
我找到了具有我需要的所有 Unicode 符号的字形的字体，但我对符号 U279C（“粗圆头向右箭头”）有问题。它是在字体文件 fonts/type1/urw/zapfding/uzdr.pfb 中找到的（编译时打印消息“uzdr.pfb（插槽 168）中存在 279C 的字形”），但构建 PDF 失败并出现错误，完整输出如下：

所以，问题是 - 我应该怎么做才能打印该字形？
