Probably you know that, multi-byte character is already allowed
as escape in LIKE. There seems no reason why we don't support
multi-byte escape character in SIMILAR TO and SUBSTRING.
Could you add the patch into next CF?
The patch doesn't contain the change of the document. But I think that
it's better to document what character is allowed as escape in LIKE,
SIMILAR TO and SUBSTRING.
