Re: wchar_t (utf-32) to NSString to utf-16

Converting between the Unicode encoding forms is all algorithmic and 
easy to implement.

For pre-10.4 support, your application could carry internal UTF-16 <-> 
UTF-32 conversion routine.

You can use the sample implementation from Unicode @ http://www.unicode.org/Public/PROGRAMS/CVTUTF/ConvertUTF.c

Alternatively, Mac OS X has another encoding conversion library iconv.

You can have it convert between UTF-16 and UTF-32.  man iconv_open 
will show you how to use the function.
