title: Unicode special characters not working on Mac OSX 10.11.5 bash terminal
body: <p>So I have been used for a very long time to typing special characters such as accented vowels and the quite common <code>ñ</code> in Spanish language when using bash on my Mac. Specifically, I used to write commit messages in Spanish via bash using these characters, no problem. </p>
  
  <p>After upgrading my Mac to OS X El Capitan 10.11.5, I noticed that as soon as I type one of these characters, the prompt changes and does not display the typed character, for instance, pressing <code>ñ</code> changes my prompt from </p>
  
  <pre><code>host:directory username  $
  </code></pre>
  
  <p>to </p>
  
  <pre><code>(arg: 1)
  </code></pre>
  
  <p>instead of simply showing <code>ñ</code> on the screen. A similar thing happens with other accentuated characters and other special characters, except the index displayed next to <code>arg</code> changes. </p>
  
  <p>While working on my MacBook Air with OSX Yosemite 10.10.5, these characters display without a problem on the command line, as I was used to. </p>
  
  <p>Both computers have the same set of encodings set in Terminal>Preferences, so that shouldn't be the issue. Also, the output of <code>locale</code> on both computers is the same, namely</p>
  
  <pre><code>LANG=
  LC_COLLATE="C"
  LC_CTYPE="C"
  LC_MESSAGES="C"
  LC_MONETARY="C"
  LC_NUMERIC="C"
  LC_TIME="C"
  LC_ALL=
  </code></pre>
  
  <p>I thought the terminal would be the only affected area through this update. It really turned into a problem when running a python script that would run perfectly on my OSX 10.10.5 Mac, would exit with encoding errors on my 10.11.5 Mac, under the SAME version of Python (3.4.3). </p>
