# How to obtain the string é by using the \detokenize command?

I failed to use "\include" with a file that contain the string "é" in its name like "réserve". so I tried the following without success

\include{\detokenize{réserve}}

After some trials I have noted that the command

\detokenize{é}

produces "Ãľ" in place of "é".

Hence the question "How to obtain the string "é" by using the \detokenize command".

Here is a minimal example

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\begin{document}
\detokenize{é}
\end{document}

You are better using file names without special characters. If you like to live dangerously, you can patch some kernel macros:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{etoolbox}

\makeatletter
\patchcmd{\include}
{\@include#1}
{\expandafter\@include\detokenize{#1}}
{}{}
\patchcmd{\@include}
{\string\@input{#1.aux}}
{\string\@input{\string\detokenize{\detokenize{#1}}.aux}}
{}{}
\makeatother

\begin{document}

\include{réservé}

\end{document}


For the further visitors who, like me, comes from google:// detokenize unicode.

\detokenize is not UTF8-friendly, but sometimes you can replace it with the following command:

\newcommand{\utffriendlydetokenize}[1]{%
\scantokens{%
\catcode\_=12%
\catcode\^=12%
\catcode\{=12%
\catcode\}=12%
\catcode\&=12%
\catcode\\$=12%
\catcode\#=12%
\catcode\~=12%
\catcode\\=12%
#1%
}%
}


However, it does not work with \include`.
