当我整合这个如何使用标准 -（连字符）作为 hyphenat 包中的 \hyp{} 命令？进入我的主文档，我收到有关翻译包中连字符使用的错误：

然后，我将其像这样包含在我的文档中：
\begin{document}
\ExplSyntaxOn
\cs_new:Npn \hyphenfix_emdash:c {---}
...
Tests.
Encoding-encoding-encoding-encoding-encoding-encoding-encoding-encoding-encoding-encoding.
\end{document}
而且它成功了！
有没有办法将其包含在我的序言中而不是文档的开头？
更新
根据评论所建议，我添加了\AtBeginDocument{，但它不起作用：
\usepackage{expl3}
\AtBeginDocument{%
\ExplSyntaxOn
\cs_new:Npn \hyphenfix_emdash:c {---}
\cs_new:Npn \hyphenfix_endash:c {--}
\cs_new:Npn \hyphenfix_discardnext:NN #1#2{#1}
\catcode`\-=\active
\cs_new_protected:Npn -{
\futurelet\hyphenfix_nexttok\hyphenfix_i:w
}
\cs_new:Npn \hyphenfix_i:w {
\cs_if_eq:NNTF{\hyphenfix_nexttok}{-}{
%discard the next `-` token
\hyphenfix_discardnext:NN{\futurelet\hyphenfix_nexttok\hyphenfix_ii:w}
}{
% from package hyphenat
\hyp
}
}
\cs_new:Npn \hyphenfix_ii:w {
\cs_if_eq:NNTF{\hyphenfix_nexttok}{-}{
\hyphenfix_discardnext:NN{\hyphenfix_emdash:c}
}{
\hyphenfix_endash:c
}
}
\ExplSyntaxOff
}
现在，它引发另一个错误：
