Odd query behavior

Hello,

I've come across an odd situation. I've had access to a database where a
the following happens:

" SELECT * FROM table WHERE name LIKE 'abc%' " returns 2 rows...

but...

" SELECT * FROM table WHERE name IN (SELECT name FROM table WHERE name
LIKE 'abc%') " returns 0 rows...

I've also tried doing a join on the column to another table that has
what appears to be the same data, and the join comes out with zero rows.
Weirder yet, I took the hash of both of the values and it came out
identical.

Now, I know the first thing you'll ask is if you can get a copy of the
data to re-produce it, and the problem is, I got a copy of the data in
question, and loaded into another server and it works fine. Both queries
return 2 rows.

I do know that server it was running on was Finnish. The database uses a
UTF8 encoding though, so I don't know what that would make any
difference.

Any ideas about things I should be looking at?

Thanks

Dan
