[erlang-questions] Changes to string module

[zxq9]

I missed it when looking through R20 release notes, but on referencing the string module I noticed a LOT of changes have happened there. String objects are now more or less based on unicode:chardata() and utf8 graphemes.

Whoever is responsible for this -- THANK YOU.

For those of us in East Asia life just got a bit easier. Not 100% easy, because what fun would that be, but this sure is a lot nicer.

Yay!
