Yes, I only used the 'disjoint representations for first-bytes and

search it with LIKE '%[BA]%', we judge that they are matched by mistake.

AFAICS, the patch does *not* make that mistake because % will not
advance over a fractional character.


Unless I hear differently, my present intention is to apply the suggested improvement universally. I'll wait a day or two before completing the patch.
