I suppose it makes sense that the situation would be better in NT. Win9x
also has the CHCP command, but you have to reboot after using it, and you
are also cautioned against using it at all, for fear of "disk corruption".
Furthermore, US versions of Windows supply only two code pages for you to
change between: CP437 and CP850.

This is interesting. What happens, then, when you try to run a
non-UCS2-aware application in the console window? That is, something that
prints only ASCII strings (without NULs between each character)? Is it
total garbage, or does it display correctly by some magic?
