Question

有没有办法为 qrcode 包添加重音字符支持？

    \documentclass[french]{article}
    \usepackage[T1]{fontenc}
    \usepackage[utf8]{inputenc}
    \usepackage{babel}
    \usepackage[]{qrcode}
    \begin{document}

    \qrcode[]{ààààççççééééùùùùïïï}% produces an error: accented characters

    \qrcode[]{Are accented characters supported by the qrcode package ?}% works well

    \end{document}

Answer 1

如果你使用支持 UTF-8 的引擎（比如 LuaTeX 或 XeTeX）编译文档，则代码可以正常工作：

% Compile with LuaLaTeX or XeLaTeX
\documentclass[french]{article}
\usepackage{fontspec}
\usepackage{babel}
\usepackage[]{qrcode}
\begin{document}

\qrcode[]{ààààççççééééùùùùïïï}% produces no error: accented characters

\bigskip
\qrcode[]{Are accented characters supported by the qrcode package ?}% works well

\end{document}
