I've written a plain [C99] test program, below. This works fine with
wcsftime() and wfprintf(). So, I guess the problem is with "wcout".
If there's a problem like fwide() with iostreams (you can't use
fwprintf and fprintf with the same stream, or change the byte/wide
mode once set), perhaps you can't output to both std::cout and
wtd::wcout? (This appears to be the case; after removing all the
std::cout usage in the previous testcase, std::wcout appears to also
output UTF-8).
Regards,
Roger
