FWIW, wchar_t isn't guaranteed to be either of these.  IIRC for gdb we
found out that there are systems that use their own special encoding, I
think Solaris.

Also, some implementations of iconv cannot convert to or from the
wchar_t encoding; though I imagine you can work around this with
appropriate template specializations to use the <wchar.h> stuff.

IMNSHO the whole area is kind of a crazy mess.  In gdb we ended up
punting on some scenarios for less-than-sane hosts and/or targets; but
gdb's needs are somewhat unusual.
