An easy sell.  Good!

In fact, it might even be nice to preserve the locale-dependent existing behavior of collating-element ranges for '[[.A.]-[.Z.]]', even while changing the simpler [A-Z] to do the encoding-based range, so that a rare user that really DID mean to get locale-dependent collation range can still do so.
