OK, but that is a change from what TR18 says: "names should use a loose
match, disregarding case, spaces and hyphen" except for the three
problematic situations it mentions. There is no character TIBETAN MARK
TSA PHRU, and I thought the whole point of loose matching is to follow
the intent of the user even in the face of certain missing or extraneous
punctuation and spacing characters, so even though it is not exactly
what they asked for, it is close enough by the traditional definition.
I realize that TR18 is not an official part of the standard, and that
TR44 is now UAX44, so is. Therefore, this is a change in the standard
that I don't believe was listed as a delta.
