| Its important to note that wchar_t != UTF16, it is a native type that can even be a single byte (and is on some 8 bit platforms).
You can't blindly stick UTF16 into a wchar_t, as you've found wchar_t on unix varients is UTF32 with native byte ordering. On Windows it happens to be UTF16 with native byte ordering so you can stuff UTF16LE directly into a (x86 based) Windows machines without problems, but that won't work on a ARM or MIPS based CE machine. Likewise, blindly copying UTF32LE into a wchar_t on Linux for x86 will work fine, but the code won't work on a Linux machine on a MIPS processor. It might work on ARM as ARM will go both ways and I presume the Linux guys used LE byte ordering but thats just a guess.

I can't say for sure - but check sizeof(wchar_t) on debian. If it's 4, then that's your answer. Just a hunch!

on Windows with version libxml2-2.7.7 I get: rc=16 url="" href="http://atest.com/" target="_blank">http://atest.com
on i386 Debian with version libxml2-2.7.8 I get: rc=16 url="">
It looks like on Debian that it has simply copied the input buffer into the output buffer: url[0] = 'h' url[1] = '\0' url[2] = 't' ...
Thanks.
