I started using FreeUDF's trim function, mainly f_rtrim. I find it adding characters, like 3 times the original characters. I am using against Firebird 1.0 Final. Any know what's wrong? Here is a sample query that is not working correctly.

select R.RDB$RELATION_NAME
,f_rtrim(R.RDB$RELATION_NAME) DB_TABLE_NAME
from RDB$RELATIONS R

HELP! I need a good Windows/Linux UDF library with functions like trimming.
