I am not sure of the level of MPI support, either! wchar_t was oppposed
in both C90 and C99, for reasons I could describe. C++ has a somewhat
different and more useful specification, which may or may not be fully
compatible. And the next versions of the standards are introducing a
completely new pair of extended character types and conversion functions
for Unicode support - I believe that C++0X introduced them for compatibility
with C1X, which may or may not ever become a standard!
God alone knows what MPI implementors make of that mess, because I have
never touched the things, few scientists are interested, and I teach the
kiddies to avoid that area like the plague. I have heard rumours that
some people use the facility, in non-portable applications.
