I don't think that reinventing the wheel for the sake of
cross-platform compatibility is a bad thing. Besides, noone
prevents anyone from writing Python extensions to make the
system codecs available to Python. The problem we face with
these, though, is that they won't be available everywhere.
The basic design decision we made for Unicode was to have it available
everywhere -- not only on platforms where Unicode is supported.
This includes a usable set of codecs for all common encodings.
The Asian codecs were just left out of the standard dist due
to size problems.
