It's the only way, but you can not manipulate a unicode string as a list
because it's *broken*. Sure, you don't realize it if you're an
english-speaking developer working only with english speakers. But that
does not make it not-broken.
And what "most developers" are content with has never been very high
praises. You'd think a dweller of the Erlang mailing list would be the
first to know it: most programmers are also content using threads and
locks, regardless of whether that's strictly correct or not.
