[I18n-sig] Fw: Codecs for Japanese character encodings

(I forwarded this to the SIG on Friday, but it failed to appear - hope you
don't all get it twice).
Tamito Kajiyama has written pure Python codecs for the two main Japanese
encodings!  Many thanks!

They include the 6879 characers in the JIS0208 character set in literal
Python dictionaries; so it should be trivial to write modified ones which
support vendor-specific extensions with a few extra characters, as long as
the extras are in Unicode.

I'm now rewriting something I did last year in-house for a customer - a
script to generate HTML tables and text files which exactly match the layout
of the code charts for JIS0208 in "CJKV Information Processing".  I ran
these through both codecs and viewed the results in IE5, and as far as I can
see the results are perfect.  I will post up my scripts when they look a bit
prettier :-)

It would be nice to put this code somewhere 'out there' so people can work
on it - not just codecs, but test suites.  How do people feel about starting
a project on www.sourceforge.net under CVS?

Since lots of us want to work on fast Asian codecs, another things we need
is a 'benchmark suite' - maybe a megabyte of Japanese text (mixing
everything - ASII, Kanji, half-width katakana?).  We can then use these pure
Python codecs as a baseline.
