At least under linux *printf() and *scanf() use proper separators on my box..
Dunno what Win* uses. Under unix, that *printf behaviour could be dangerous
since it can lead to generation of .ps files that can't be parsed by PS
interpreters (AW has a means to overcome it - i.e. using "." as fraction
separator).

What problem did you face? That under Win* "." is unconditionally used as
fraction separator for any locale? Is it only aestetical problem? If yes, I
think windows users can live with it.

Do you mean "how to construct string that can be used as locale name for
'setlocale'"? If yes, XAP_EncodingManager already provides this info (provided
someone wrote backend for windows).
