Hi,

I have a problem with lower/upper functions.
It seems that the lower function modifies some of the unicode
characters(german, hungarian, romanian) and the upper case function
modifies other(hindi).

When i say modifies i don't mean it transforms the the character in it's
lower/upper form. It simply transforms some of the characters into
mush(the charaters are distorted or transformed to "")

To test this i used one special character on each record and used
"SELECT x, LOWER(x), UPPER(x) FROM test_unicode"
Anyhow... i attached the dump so you can test it yourself.

What do you think is the problem?

Thanks,
xayk
