The idea of character streams is for supporting streams which already handle the
byte to UNICODE character translation for you.  I am not familiar with Python,
but I assume there must be some sort of 16 bit wide character set that is Unicode
compliant.  This I feel is all that David is trying to add to SAX, not something
Java specific.  Nevertheless, if a particular language has no Unicode support
whatsoever in the first place, then you are SOL for supporting XML in the first
place.

Readers (or character streams) may have much more efficient byte to character
translation implementations than anything the parser could provide in the first
place.

I think the addition of character streams to SAX is a very good thing.
