Yet more evidence that a whitelist approach to IDN (“you can only use these characters”) is much to be preferred by registries to a blacklist approach (“you can use any character except these few”).

Once Unicode was made big enough to accommodate Chinese writing (and its derivatives), it was inevitable that it would eventually accumulate a lot of blatantly unnecessary garbage until sooner or later it will become a wretchedly unmaintainable morass of useless cruft.
I mean, there’s plenty of room left, right? What’s it hurt? (Other than the sanity of everyone who has to support Unicode for any reason, that is. Haha.)
It started with _relatively_ sane (albeit clearly unnecessary) stuff, like little-known and seldom-used writing systems that nonetheless do represent real languages, bits of not-entirely-mainstream math notation, a set of music notes, …
But you knew it couldn’t stop there. You knew somebody would eventually argue for the inclusion of popular Dingbats, and it’s all downhill from there.
