With all due respect, I think you need to rephrase the following claim to avoid problems. In 2.1.2.4 it says:
To our knowledge, we have not released a single MySQL version with any known ``fatal'' repeatable bugs. (A ``fatal'' bug is something that crashes MySQL under normal usage, produces incorrect answers for normal queries, or has a security problem.)
I was distressed to see that 4.1.10 does not include a bug fix for an acknowledged bug in the way '=' works with utf8 & Windows 2000/XP in 4.1.9 & 4.1.8.
http://bugs.mysql.com/bug.php?id=7878
The bug is simply that:
SELECT * FROM extable1 WHERE col1 = 'teste'
if col1 values include 'teste', 'testé', 'testé'
it will only match one of the two 'testé'
(utf_general_ci, Windows 2000 or XP, at least 4.1.8-4.1.10 now)
I certainly think this is an incorrect answer for a normal query!
I hope this has been helpful. (If I should post this directly in the documentation comments, please tell me.)
