Well, if you never heard anyone complaining about [Char] and never had
any problem with it's slowness, you're probably not in a field where
the efficiency of a Unicode library is really a concern, that's for
sure. (I know that the _main_ problem with [Char] wasn't random
access, but you must admit [Char] isn't really a good example to speak
about efficiency problems)
