One file lib to conv utf8 (char*) to wchar_t?
<p>I am using <a href="http://sourceforge.net/projects/libjson/" rel="nofollow">libjson</a> which is awesome. The only problem I have is I need to convert an utf8 string (<code>char*</code>) to a wide char string (<code>wchar_t*</code>). I googled and tried 3 different libs and they ALL failed (due to missing headers).</p>

<p>I don't need anything fancy. Just a one way conversion. How do I do this?</p>
