Agreed.

I disagree with this, though.  It's not that much of a hardship to add an
"L" before your character constants; certainly not enough to warrant
subclassing a class without a virtual dtor (and duplicating all the
constructors and all the functions which return a string as a function
result).

I think I'd go for using straight std::wstring, and define the characters
in those wstrings to be UTF-16 encoded (whatever the current C locale
says).  Leave it up to the application either to set a locale in which
wchar_t is UTF-16 (in which case the RTL functions will behave sensibly),
or not (in which case the application will have to hand crank some things).
