Since most of that work is for an exceptional case, maybe it'd be safer
(although slower) to structure the function as
setlocale
call strxfrm (and that's it)
setlocale back
if there wasn't enough space
make a new buffer
setlocale
call strxfrm (and that's it)
setlocale back
Probably putting the sl/strxfrm/sl into its own function.
