因此，我一直在尝试将俄语添加到 Overleaf 的模板中。它有一个如下所示的自定义类：
\ProvidesClass{clean_cv}[2021/07/28 v1.0.0 'CleanCV' Class]

我按照 Overleaf 教程将俄语添加到乳胶中，并将这些行添加到我的.tex文件中。

\author{ASDXCASD ФЫВФЫВ}
\headlineposition{ASDASD ФЫВФЫВ}
\begin{document}
\maketitle
\end{document}
但后来它给了我这些错误：
Font T2A/XCharter-TOsF/m/it/10.95=XCharter1-Italic-tosf-t2a at 9.85492pt not loadable: Metric (TFM) file not found.
<to be read again>
relax
l.22 \maketitle
I wasn't able to read the size data for this font,
so I will ignore the font specification.
[Wizards can fix TFM files using TFtoPL/PLtoTF.]
You might try inserting a different font spec;
e.g., type `I\font<same font id>=<substitute font name>'.
pdfTeX error (font expansion): invalid font identifier.
MT@font ->T2A/XCharter-TOsF/m/it/10.95
l.22 \maketitle
我该如何修复此错误？这是向此自定义类添加俄语支持的正确方法吗？
答案1
我认为这是 XCharter 维护者打包时的错误。在我的计算机上，我保留了 2012 年发布的 TeX Live，结果
> locate XCharter1-Italic-tosf-t2a.tfm
/usr/local/texlive/2017/texmf-dist/fonts/tfm/public/xcharter/XCharter1-Italic-tosf-t2a.tfm
/usr/local/texlive/2018/texmf-dist/fonts/tfm/public/xcharter/XCharter1-Italic-tosf-t2a.tfm
/usr/local/texlive/2019/texmf-dist/fonts/tfm/public/xcharter/XCharter1-Italic-tosf-t2a.tfm
/usr/local/texlive/2021/texmf-dist/fonts/tfm/public/xcharter/XCharter1-Italic-tosf-t2a.tfm
> locate XCharter1-Italic-tosf-t2a.vf
/usr/local/texlive/2017/texmf-dist/fonts/vf/public/xcharter/XCharter1-Italic-tosf-t2a.vf
/usr/local/texlive/2018/texmf-dist/fonts/vf/public/xcharter/XCharter1-Italic-tosf-t2a.vf
/usr/local/texlive/2019/texmf-dist/fonts/vf/public/xcharter/XCharter1-Italic-tosf-t2a.vf
/usr/local/texlive/2021/texmf-dist/fonts/vf/public/xcharter/XCharter1-Italic-tosf-t2a.vf
因此您会看到 TeX Live 2020（Overleaf 使用）中缺少字体。现在更新它已经太晚了，因为 TeX Live 2020 已冻结，但您可以使用 TeX Live 2018 进行编译（我相信 Overleaf 可以做到这一点）。
顺便说一句，使用 TeX Live 2019 和 2021 进行编译会失败，原因是
! TeX capacity exceeded, sorry [max level recursion of virtual fonts=10].
\AtBegShi@Output ...ipout \box \AtBeginShipoutBox
\fi \fi
一种解决方法是删除该osf选项，否则，测试将无法与我拥有的每个支持的 TeX Live 版本XCharter（特别是 TL 2020）兼容。
已向维护人员提交了一份错误报告，但没有机会使其与 TeX Live 2020 一起工作（如果您不做大量工作）。
