title: git converts characters like ✓ and ✗ to underscore (_)
body: <p>I have a git repository which contains my .bashrc and therefore the following content:</p>
  
  <pre><code>...
  PROMPT_DIRTY=" \[\033[1;31m\]✗\[\033[0m\]"
  PROMPT_CLEAN=" \[\033[1;32m\]✓\[\033[0m\]"
  ...
  </code></pre>
  
  <p>If I'm cloning this repo on an Archlinux distribution I get exactly this (the above) output. But if I'm cloning the repo on a Debian (tried multiple versions) or FreeBSD 10.0 then I'm getting the following:</p>
  
  <pre><code>...
  PROMPT_DIRTY=" \[\033[1;31m\]_\[\033[0m\]"
  PROMPT_CLEAN=" \[\033[1;32m\]_\[\033[0m\]"
  ...
  </code></pre>
  
  <p>I.e. the special chars ✓ and ✗ are converted into an underscore (_). </p>
  
  <p>Does someone know why this is happening? I would like to have the original special non-alphanumerical characters instead of the underscore.</p>
