I try below sample but can not pass compile:
\documentclass{article}
\begin{document}
├── version.txt
└── visible_windows.zip
\end{document}
Error:
! Missing $ inserted.
<inserted text>
$
l.4 └── visible_
windows.zip
? x
content is output of tree command from linux.
You probably want something like this:
\documentclass{article}
\usepackage{pmboxdraw}
\begin{document}
\begin{verbatim}
├── version.txt
└── visible_windows.zip
\end{verbatim}
\end{document}
In OpTeX, _ is normal character:
\fontfam[stix]
\obeylines
├── version.txt
└── visible_windows.zip
\bye
It generates, what you want.
_and in latex and plain you need to change both, but to suggest that some formats can do this and some not is ...._is set with catcode 8. This thread is only one example of such mistakes. I know that If you will design a new format from scratch then you don't set the catcode 8 to_in order to avoid such user mistakes. But, of course, LaTeX must keep old principles.
