Hi,
When using the upper() function in a varchar column containing Greek
data (i.e. ISO-8859-7, UNICODE, WIN1253), we see no effect in the
original string.
Example
select upper('My LowerCase string in Greek') from test
it returns always the original string.

Is there any way to overcome this problem? We think that Firebird is
superb, but this (if we cannot resolve it) is a major weakness (at
least for Greek Customers)...

Thanks in advance!
