Ok, does that mean there could possibly be a loss of data, for characters that need two bytes? Or have I got the wrong end of the stick when it comes to storing Unicode strings?

I've just tried using 'wcstombs()' to convert my wide string to a multi-byte string, which I can then BAD_CAST to xmlChar. Is this the correct way of doing this? I just tried passing a random arabic string through wcstombs() and it fails, because it cannot a wide character.

I also tried using iconv (although I wasn't sure what my input code should be utf-16?), this also failed, giving me EILSEQ, again a character it cannot convert.

How should I convert my random arabic string to utf-8? Is it possible?
