This certainly explains it. With locale enabled, LIKE does not use
indexes because we can't figure out how to do the indexing trick with
non-ASCII character sets because we can't figure out the maximum
character value for a particular encoding.

We didn't do the check in 6.4.*, and LIKE was not returning the proper
results for queries at those sites that used locale.
