We are using a firebird database under Linux.

Our problem is that can't perform a text-search when there are
specials characters (ÆØÅ) in the fields because we cant upper these
characters.

I have tried to install a UDF which have a ANSI_UPPER function but i
doesnt solve the problem, the result looks like this.

SQL Sentence "SELECT UDF_ANSIUPPER(NAVN1) FROM KUNDER"

Result:
A. CHRISTENSEN
A. Engstrøm

Is there anybody who have a function which can convert these
characters(æøå) to uppercase
