Fonts & Character Sets ⇒ Left Right Arrow with Vertical Stroke

[Maskarados]

Hi,
I have a problem with symbol called Left Right Arrow with Vertical Stroke (unicode 0x21f9). I can't find any information how to include it in my Latex documents, what command should I use (\nvleftrightarrow ?), what package to include? Any ideas? I was searching on google but no success. Help me please!

Hi,

I did a quick search on the Comprehensive LateX symbol list, but couldn't find the exact symbol you are looking for. In any case, you can define your own symbol, something along these lines:

Code: Select all

\documentclass{article}
\usepackage{amssymb,amsmath}

\newlength\mylen
\settowidth\mylen{$\leftrightarrow$}
\newcommand\NLRArrow{%
  \leftrightarrow\kern-0.55\mylen\vline height 1.2ex depth -0.4pt\kern0.55\mylen}

\begin{document}

$a\NLRArrow b$

\[a\NLRArrow b\]

\end{document}

Thanks a lot, it works very well for me!
