You get me wrong. I tried to to say it works for latin5 and unicode. When I look at the latin-n implementation of PostgreSQL, see that there doesn't exist a far difference between 'em. So there shouldn't be a problem with latin-n encodings. But, as I try to explain, I don't have so much knowledge on unicode characters and cannot claim an exact answer about it. > It might be that there are degrees of not-working-ness here, but before > adopting a partial solution I would like to see some reasoning why it > won't make things worse for other people.

Furthermore, I just used the methods already in the code. If it'll cause any crashes in the server side, it won't be my fault.

Here's a short list of cases I tried with both latin5 and unicode charsets: - lower/upper functions with Turkish characters. - ILIKE matches with both lower and upper case Turkish characters. (Above testes succeeded for non-Turkish characters too.) Regards. ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
