If you can get a wchar_t * out of the app then that can be simply cast
to a packedstring, this is quite speedy.
if you use mbsrtowcs(3) and friends to do the conversion from char *
then you get properly localized text via locale settings for free :)
I have used this sort of thing for interfacing haskell to libraries
where honoring locale was important in the past.
