Hello Didier,

Since you are working on internationalization, I would suggest _not_ 
dropping the FONT directive for your case. Languages as Cyrillic, 
Greek or Portuguese (among others) are not 100% supported in CP865 
nor in CP437; and that's before even thinking about the built-in BIOS 
language. Additionally, some "accented" uppercase characters are also 
not supported in CP437.  

I could think of an experiment so to be able to select the adequate 
codepage for each language, but I think it would be better if someone 
else could post the adequate procedure.

Best Regards,
