16 bit wchar_t support in linux and gcc

Question

I'm working on a cross platform project that complies with the -fshort-wchar flag so the wchar_t type is 2 byte. On Windows that's fine but on Linux the means no libc functions like printf or fprintf.

I've been looking for a good solution for some time now and frankly getting a little desperate.

Does anyone have a good idea except avoid using libc functions altogether?

If you're working with wide characters, you must use [`wprintf`](http://linux.die.net/man/3/wprintf) instead of `printf`. — Michael Foukarakis, Mar 11 '13 at 12:00
the problem is that in linux (gcc) wprintf only works with 32 bit wchar_t — Daniel Miron, Mar 11 '13 at 14:28
That's because the representation of `wchar_t` is dependent on platform and locale. The one your program uses must match the one your libc supports. Read [this](http://icu-project.org/docs/papers/unicode_wchar_t.html) for some more info. — Michael Foukarakis, Mar 11 '13 at 15:13
is there any why to get a libc implementation that works with 16 bit wchar_t ? — Daniel Miron, Mar 11 '13 at 16:03

This inside an #ifdef might help (i haven't tested it though):

typedef __u16 wchar_t16;
