Last minute edit:
src/test/mb seems a little bit old. I've tested SQL files in
src/test/mb/sql with the expected results in src/test/mb/expected
manually and it worked. (Output files need a little bit editing, like
removing lines similar to "CREATE TABLE".) But it'll be better if any
EUC users will try 'em manually too.

According to what IRC folks, yes.

Furthermore, there're some unofficial ICU patches for PostgreSQL
around. Like the one @

As I mentioned in the above, it seems like it's working for other ones too.

You don't want to commit this patch because it breaks[*] EUC like
encodings. But OTOH, it fixes LatinN and UNICODE encodings. I'm really
wondering, while we're trying to protect the EUC encodings still
working, why there's not any EUC users around to take care of EUC
tests? Doesn't EUC have any problems? Do ILIKE, upper/lower work for
them properly?

[*] If I didn't make a mistake, manual tests succeded for EUC like
encodings too.

You can think the reverse of the subject too. Think LatinN and UNICODE
as working and somebody submitted a patch which fixes EUC encodings by
breaking the previous ones. What will be the reaction of PostgreSQL
team in this situation?
