Hi Helen,

The problem was that when using special characters (é, ç, etc...) and
the field is UNICODE_FSS, Firebird seems to be working in overtime and
the CPU resources jumps to 100% and stays there until you do a forced
shutdown. I can reproduce the problem easily and posted it in the bug
tracker. I use UNICODE_FSS in one of my databases and if I try to to
server's CPU process goes to 100% and stays there(I wouldn't know for
how long, since I kill the server after waiting for 30 minutes). And,
in my test database, I only have 20,000 records. And, if I use a
normal english character, the query returns a result instantly.
