NSURL encoding using iso-8859-1 instead of UTF8
<p>I need to convert a NSString to a NSURL using the iso-8859-1 instead of UTF8 (like here: <a href="http://stackoverflow.com/questions/1927127/re-encode-url-from-utf-8-encoded-to-iso-8859-1-encoded">http://stackoverflow.com/questions/1927127/re-encode-url-from-utf-8-encoded-to-iso-8859-1-encoded</a>) but i don't know how to achieve it.</p>

<p>For example:</p>

<pre><code>http://www.example.com/català 
</code></pre>

<p>should be</p>

<pre><code>http://www.example.com/catal%E1
</code></pre>

<p>insted of</p>

<pre><code>http://www.example.com/catal%C3%A0
</code></pre>

<p>Thanks in advice!</p>
