Dear list members, I'm using PostgreSQL 8.0.8, witha UTF8 database. I'm using a regular expression to check if some value is in a string: field ~* 'somevalue' It works ok for 'somevalue', 'SoMeVaLuE somedata'... But if I check field ~* 'á' It works for 'áeiou', but fails for 'Áeiou'. Seems that case-insensitive regular expressions don't know that 'Á' is 'á' uppercased. Same for 'ñ' and 'Ñ'. To test, if I select upper('áeiou'), it returns 'ÁEIOU', that is ok. So the 'disconnection' between 'á' and 'Á' just occurs in regular expressions, not in other case-insensitive functions. Is there any solution to avoid this? Thanks. -- Sergio Cinos Info3 Servicios Informáticos S.L. sergio.cinos@xxxxxxxxx - www.info3.com
