I might be asking a silly question here, but I've been working with this for a few days, and I've narrowed my issues down to this:
The wide character versions of the printf functions are failing with various non-ascii characters, as can be seen with the following code:
#include <stdarg.h> #include <wchar.h>
int main() { wchar_t buf[20]; va_list ap; return vswprintf(buf, 20, L"トネヘ", ap); }
In case the above doesn't properly survive the e-mail, that's just three random Japanese characters in the test string. This code returns -1 instead of the 3 that I would expect by looking at it. The same is true for various other sets of non-ascii characters and various other wide character printf functions.
I'm using Xcode 2.4.1 under 10.4.10 on an Intel machine. This is with g++ version 4.0.1 (build 5367).
Any ideas?
