This is dated 2004. Basically, they considered several options, tried 
out 4, and ended up sticking with char[] (sequences) as UTF-16 with char 
= 16 bit code unit and added 32-bit Character(int) class for low-level 
manipulation of code points.

I did not see the indexing problem mentioned. I get the impression that 
they encourage sequence forward-backward iteration (cursor-based access) 
rather than random-access indexing.
