Re: int21 handling

[Eric Pouech]

Use wide characters and manual wide character conversions.
DOS routines use OEM code page and not ANSI code page and
Wine uses wide characters as default character set, anyway.
Regarding this part, I think we'd better rely for int21 support to the
SetFileApisToOEM and SetFileApisToANSI APIs (and or course implementing 
them correctly).
I'd suggest changing the oem_files_api to a krnl_file_api_codepage (or 
something like this) which would be set to either CP_ANSI or CP_OEM and 
use this variable in most of file related A functions (instead of our 
current CP_ANSI). Then we would set OEM APIs on int21 entry (and reset 
to the old mode on exit). I assume we hold a lock while executing the 
int21 API, so preventing some multi-threading issues on this.
Any comment before I go on?
