[BUGS] bug in 7.4.2, concern unicode and russian content of db

[Alexander S.]

There is bug in 7.4.2, concerning  unicode and russian letters. For db 
in unicode russian data doesn`t order in alphabetical order (rows group 
with the same first letter but not in alphabetical order).
SELECT "person" from my_table ORDER BY "person";
Rows group in such order (approximately): Ð-Ð-Ð-Ð-Ð, but must be : 
Ð-Ð-Ð-Ð-Ð.
For english letters all looks fine. For db in koi8r encoding also all 
works right. So, I CANNOT use unicode with russian content of db in 
postgres.  Is it bug or not?
