我最近更新了我的 Miktex 包，正如预期的那样，这破坏了我之前使用的 Latex 页面模板。
在下面的 MWE 中，我可以混合拉丁字符和西里尔字符……但后者显示为丑陋的光栅化。
先前显示的矢量化字符会删除“%ERROR:”，但现在它们会抛出错误。
如何修复这个问题而不需要直接输入字符？
\documentclass[pdftex,12pt,russian,english,dutch]{article}
\usepackage[OT2,OT1]{fontenc}
\usepackage{babel}
\usepackage{xpatch}
% ERROR : \xpatchcmd{\cyrillictext}{\selectfont}{\fontfamily{wncyr}\selectfont}{}{}
% ERROR : \let\cyr\cyrillictext
\begin{document}
This is text in the Latin alphabet !\\
Next are the Cyrillic characters for Russian :\\
\begin{tabular}{@{}ll@{}}
\foreignlanguage{russian}{a} & \foreignlanguage{russian}{P}\\
\foreignlanguage{russian}{A} & \foreignlanguage{russian}{r}\\

自 2020 年 2 月起，LaTeX 内核内置了字体系列替换机制。
\documentclass[12pt,russian,english,dutch]{article}
\usepackage[OT2,OT1]{fontenc}
\usepackage{babel}
\DeclareFontFamilySubstitution{OT2}{cmr}{wncyr}
