title: Notepad++ - change escape character
body: <p>In PL\SQL code which I am editing with Notepad++ I have following:</p>
  
  <pre><code>where REGEXP_SUBSTR (a.val, '(\d+)\', 1, 1, NULL, 1) = b.key
  </code></pre>
  
  <p>Because of <code>\'</code> Notepad++ does not interpret <code>'</code> as quote closure and rest of source do not have syntax coloring - it has grey color like quoted text.<br>
  Is there any way to tell Notepad++ to do not interpret <code>\</code> as escape character, thus <code>\'</code> will be interpreted as valid end of quote?<br>
  I was searching program preferences, but without any success.</p>
  
  <p><strong>EDIT</strong><br>
  Strange. When I open new new file, type this line, choose <em>Language > S > SQL</em> then text is highlighted OK. But when I change tab and then return I have bad coloring again.  Choosing <em>Language > S > SQL</em> again makes no difference.</p>
