Bug reference:      2193
Logged by:          Andras Got

PostgreSQL version: 8.0.4, 8.1.1
Operating system:   FreeBSD and Linux
Description:        INITCAP and LOWER/UPPER string conversion error


I'm trying to select with LOWER/UPPER and INITCAP but they return bad values
after hungarian accentuated letters (e.g:       ). The bad is
value is a capital letter. This makes almost impossible to compare strings
from an input with ones in the table. Also LOWER returns a big capital
letter for the first letter of the word. UPPER doesn't really converts some
chars to uppercase, e.g: , , .

I'd like to something like this with PHP:
"SELECT id FROM table WHERE LOWER(name) = '".strtolower($name)."';

I tried with LATIN2 encoding and the same happened.

The first capital letter probleml looks like to be solved, but the
accentuated letter problem still exists.

Thank you for your time,
