Kinda half-sad it didn't make it. Would have been cool to able to "see" behind the curtains of UTF strings. As it is now, you can only paste a UTF string in a UTF aware environment, and you also need the correct fonts etc.

It would have been cool to be able to incrementally upgrade legacy environments to use UTF via UTF-7. Unaware parts would just have displayed the encoding. String lengths would have sort of worked.

(All of these things would of course have come with horrible drawbacks, so in that alternative universe I might have been cursing that we got UTF-7...)
