自定义图标字体无法与 XeTeX/fontspec 一起使用

自定义图标字体无法与 XeTeX/fontspec 一起使用

我使用以下方法制作了自定义图标字体Fontself 制作者，在拉丁字符的插槽中只包含几个图标。对于这个 MWE，我制作了一个字体鸭脸（从我的服务器下载) 仅包含一个空格字符和D一个鸭子字母*。

% !TeX program = xelatex
\documentclass{scrartcl}

\usepackage{fontspec}
\newfontfamily\iconfont{Duck Face}

\begin{document}
\Huge
D
\par
\iconfont
D
\par
\end{document}

然而编译失败

Error 11 (driver return code) generating output;
file bfs-test.pdf may not be valid.
SyncTeX written on bfs-test.synctex.gz.
Transcript written on bfs-test.log.

但 LOG 中没有进一步的（可理解的）错误消息。自定义字体有什么问题？或者 XeTeX 只能加载包含一定范围字符的字体？

答案1

FontForge 的fontlint报告：

A point in D is outside the font bounding box data.
ERROR      2 Self-intersecting glyph
ERROR      5 Missing points at extrema
ERROR     34 Bad 'CFF ' table
ERROR     80 Missing BlueValues entry in PostScript Private dictionary
FAIL         DuckFace.otf

幸运的是，FontForge 可以修复和报告许多错误。我经常通过单击File和来修复字体Generate Fonts，从而以不同的名称制作（修复的）副本。在这种情况下，FontForge 建议使用名称DuckFaceRegular.otf，并且新生成的字体可与 xetex 和 luatex 一起使用：

\documentclass{scrartcl}
\usepackage{fontspec}
\newfontface\iconfont{DuckFaceRegular.otf}
\begin{document}
\Huge
D

\iconfont
D
\end{document}

输出

奇怪的是，fontlint新生成的字体报告了大多数相同的错误和一些新错误，但由于我不明白的原因，它们对于文件编译不再是致命的.tex：

The advance width of space (290) does not match the font's advanceWidthMax (579) and this is a fixed pitch font
A point in D is outside the font bounding box data.
The advance width of uni00A0 (290) does not match the font's advanceWidthMax (579) and this is a fixed pitch font
ERROR      2 Self-intersecting glyph
ERROR      5 Missing points at extrema
ERROR     34 Bad 'CFF ' table
FAIL         DuckFaceRegular.otf

xelatex --no-pdf file

运行没有问题，但是当使用

xdvipdfmx -vvv

转换生成的 xdv 文件时，您会看到分段错误和如下所示的日志，该日志在放弃之前会给出有关字体文件中错误的几个警告：
