This still allows only one character set at any given time. For
example, if you have a buffer in Latin-1 and another in Cyrillic,
you'd need to switch the codepage each time you switch the buffer.
What if you want both buffers displayed at the same time in two
different windows? What if you want to mix them in the same buffer?
Emacs lets you do all that without any extra codepages, and without
switching them, albeit for a price of reduced legibility in some of
the languages.

Will those work in a Windows DOS box? I doubt that.
Besides, asking people to mess with their system's display drivers is
not my idea of seamless package installation. I've chosen the
specific method used by Emacs for supporting multiple character sets
because it doesn't require _anything_ from the user, as far as the
system setup is concerned. I did consider using SVGA features for
nicer support of fonts (Emacs could generate characters itself,
without any need for external codepages), but dropped the idea after
learning that this won't work on Windows. With most DJGPP users
working mostly on Windows these days, it just didn't make sense to
spend my time on a feature that 90% of users won't ever benefit from.
