Hmm... the implementation of wcsftime() in msvcrt seems to be
completely broken.
I ran the attached test (localetest.c) and got the following results.
The point is that wcsftime() returns the same character codes as strftime()
i.e, the result is not an unicode string :-(
The bug might be fixed in recently msvcrts in VC2005 or VC2008,
but at least mingw uses the old broken C runtime. We'd better to
use strftime() and multiple conversions to avoid the Microsoft's bug.

NOTE: There is another problem that specified encoding is ignored
by the functions. The result encoding is always platform default one.
