title: Remove Unicode characters from textfiles - sed , other Bash/shell methods
body: <p>How do I remove Unicode characters from a bunch of text files in the terminal?</p>
  <p>I've tried this, but it didn't work:</p>
  <pre class="lang-none prettyprint-override"><code>sed 'g/\u'U+200E'//' -i *.txt
  </code></pre>
  <p>I need to remove these Unicode characters from the text files:</p>
  <pre class="lang-none prettyprint-override"><code>U+0091 - sort of weird &quot;control&quot; space
  U+0092 - same sort of weird &quot;control&quot; space
  A0 - non-space break
  U+200E - left to right mark
  </code></pre>
