how to search a japanese pdf file with ios
<p>I can search english pdf files by scanning the 'Tj' and 'TJ' flags.
like this: <a href="http://www.random-ideas.net/posts/42" rel="nofollow">http://www.random-ideas.net/posts/42</a></p>

<p>But i can not search japanese pdf file.
The result of scanning is like these:</p>

<blockquote>
  <p>C   ¥ ¢ *   £  y y         y   y<br>
  y w ù › C   ¥ ¢ *   £ y     y  y ¹ Ñ Ä
  ¢ £ ž › C t x | Â © µ Ä ¤ Ã   » | ¯ ï
  Í € å “ ž · ï Ò å s r w t €</p>
</blockquote>

<p>I have tried</p>

<pre><code>NSString *destString = [data stringByReplacingPercentEscapesUsingEncoding:kCFStringEncodingUnicode];
</code></pre>

<p>and</p>

<pre><code>NSString* destString = [NSString stringWithCString:(const char*)CGPDFStringGetBytePtr(string) encoding:kCFStringEncodingUnicode];
</code></pre>

<p>but it didnt work.
How to get correct encoding string?</p>
