I think this should be a no-brainer, but just in case... This function is the generic function for changing the case (upper, lower, fold, title) of a character. It is no longer used in core, is not used in cpan, and its API exposes that we currently use swashes for this purpose. We want to be able to change to not use swashes, and so the API would be wrong. It seems clear to me that this should be deprecated. If we do, can we move it to mathoms at the same time?Thread Next
