背頁：產生參考書目時發生錯誤 未定義控制序列 \printbibliography

\printbibliography我在我的 Overleaf 文件上工作得很好，直到在使用生成參考列表後出現以下錯誤時插入引文：

Undefined control sequence.                      main.tex line 60
The compiler is having trouble understanding a command you have used. Check that the command is spelled correctly. If the command is part of a package, make sure you have included the package in your preamble using \usepackage{...}.
namepartfamily ->Zim\x 
                        {fffd}\x {fffd}nyi
l.60 \end
         {document}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

\printbibliography註解掉後此錯誤消失，但不會產生參考清單。我可以確認我添加了所有必需的包。請參閱下面的文件：

\documentclass[a4paper,10pt]{report}
\usepackage{biblatex}
\addbibresource{references.bib}
\usepackage{graphicx}
\usepackage[top=25mm, bottom=25mm, left=25mm, right=25mm]{geometry}

你的.bib文件可能包含這樣的行

author  = {József Zimányi},

（找出名字的偵探工作的所有學分都歸於林蓮子在評論）。您的文件很可能.bib採用 UTF-8 或其他非 ASCII 編碼進行編碼。

但對於你的序言（以及 Overleaf 上過時的 TeX 系統），LaTeX 只需要 US-ASCII 輸入（更新的 LaTeX 將使用 UTF-8 作為預設編碼）。讓一切恢復正常最簡單的方法是告訴 LaTeX 你想使用 UTF-8

\usepackage[utf8]{inputenc}

您可能需要清除快取（請參閱https://www.overleaf.com/learn/how-to/Clearing_the_cache）之後您可以乾淨地重新編譯，但是您應該獲得所需的輸出。
