I have done some more checking and I might have been wrong about the Ubuntu and Linux in general. It looks like the formatting strings are incompatible between MSVC and *NIX. It appears that either %S (SUSv2) or %ls (C99) is needed on *NIX. MSVC switches the meaning of %s for wprintf() (http://linux.die.net/man/3/printf).
