Hi Philip,
before running your test next time try this:
vi /etc/my.cnf
insert into this file:
[mysqld]
default-character-set = swe7
then stop mysql (mysqladmin shutdown)
and restart (safe_mysqld)
then try your test again. It worked fine for me.

I'd appreciate any help understanding why ö = ] in this case.

Hi Makis,
default-character-set = greek
Try that, best wishes,
Ken
P.S. also for anyone else asking here are all the charsets included
in MySQL by default. You can also create your own.
mysql show variables like char%;
++

| Variable_name | Value

RE: SELECT w/LIKE on Swedish character ö finds ], why?
I have the same problem with Greeks, it is a bug of MySQL.
Try:
1) Create the fields of the table with BINARY option.
2) Use LIKE with BINARY option (slower)
BINARY doesn't make the uppercase convertion.

If I were to take a wild guess I would say that the lower 7 bits of ö
and ] match. Which would mean that this isn't really text, ie 7-bit
ASCII, but really BINARY data. Which means either you need create
table simple (name varchar(255) BINARY NOT NULL); or create table
simple (name tinyblob NOT NULL);
Give thoses a try.

Jim,
Thanks for the suggestion, but I already checked that and got no joy --
ö = 0xf6 = 0110
] = 0x5d = 01011101
