Wstrings are strings of wchar_t, which are 4 bytes wide on 10.3. I can't
however see any definition of what each wchar_t actually contains, but
they're probably UTF-32. Note that the contents of wchar_t is *very*
implementation dependent. (Which might explain the documentation's
reticence.)
Apple has various converters in CoreFoundation and Foundation, but none of
them (AFAICS) can cope with UTF-32. However doing so yourself is a simple
matter of programming, and you should probably look at
<URL:http://www.unicode.org/faq/utf_bom.html>. They've even got links to
sample code.
Cheers,
Chris
