我正在尝试用乌克兰语写一份文件，但不知何故我不能再使用 cleveref 包了。
以下是我的示例：
\documentclass[twocolumn]{article}
\usepackage{fontspec}
\usepackage{polyglossia}
\setmainlanguage{ukrainian}
\setotherlanguage{english}
\usepackage[backend=biber,language=ukrainian,autolang=other]{biblatex}
\setmainfont{CMU Serif}
\usepackage{hyperref}
\renewcommand{\cyrr}{р}
\renewcommand{\cyro}{о}
\renewcommand{\cyrz}{з}
\renewcommand{\cyrd}{д}
\usepackage[ukrainian]{cleveref}
\usepackage[inline]{enumitem}
\begin{document}
\section{Підсумки}
\label{sec:summary}
\cref{sec:summary}
\end{document}
该文档为我编译，因为 cref 生成标签“розд. 1”。
但是如果我删除愚蠢的 \renewcommand{cyrd}，我会出现以下错误：
<long log>
(./test.out) (./test.out)
(/usr/share/texlive/texmf-dist/tex/generic/oberdiek/se-ascii-print.def)
! LaTeX Error: Command \cyrd unavailable in encoding TU.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.24 \cref{sec:summary}
No pages of output.
使 cleveref 工作的正确方法是什么？
答案1
如果你仔细观察cleveref.sty，ukrainian你会看到

并且不直接支持西里尔字母输入（俄语也是如此）。
使用xecyr 可能解决问题，但也可能造成更大的损害。
