问题
I want to insert a file directory diagram created by tree command using verbatim enviroment. But in the output document, only file names are kept, and the connection lines are disapeared.
\documentclass{article}
\usepackage{fancyvrb}
\begin{document}
\begin{Verbatim}
.
├── app
├── bakery
├── build
├── CHANGELOG.md
├── composer.json
├── composer.lock
├── docker
├── sponsors
├── STYLE-GUIDE.md
└── webserver-configs
\end{Verbatim}
\end{document}
I have tried using fancyvrb package by setting showtabs true, but the connection lines are still not printed in the document.
Is there any way?

The problem is that these unicode characters are not included in the default mono font. If you use an unicode-capable engine, such as xelatex, and a font which contains them, e.g. DejaVu Sans Mono, the will be visible in the document:
% !TeX TS-program = xelatex
\documentclass{article}
\usepackage{fancyvrb}
\usepackage{fontspec}
\setmonofont{DejaVu Sans Mono}
\begin{document}
\begin{Verbatim}
.
├── app
├── bakery
├── build
├── CHANGELOG.md
├── composer.json
├── composer.lock
├── docker
├── sponsors
├── STYLE-GUIDE.md
└── webserver-configs
\end{Verbatim}
\end{document}
If you prefer pdflatex, the pmboxdraw package can be used:
\documentclass{article}
\usepackage{fancyvrb}
\usepackage[utf8]{inputenc}
\usepackage{pmboxdraw}
\begin{document}
\begin{Verbatim}
.
├── app
├── bakery
├── build
├── CHANGELOG.md
├── composer.json
├── composer.lock
├── docker
├── sponsors
├── STYLE-GUIDE.md
└── webserver-configs
\end{Verbatim}
\end{document}
