how to insert pipe symbol in TeX?

How to insert pipe symbol | in TeX (LaTeX)?

Solution

  • The pipe symbol may be used directly in the input and will produce the desired output if you use T1 font encoding. For example:

    \documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
Pipe sign: |
\end{document}

    See Special LaTeX characters for such an example with its output and more information.
