IMHO it's a bad decision to have the standard unicode string (be it
WideString or UTF8String) functionality redefined to "Code units"
(subcodes) instead of "code points" (characters). I feel it would have
been better to have the old notation (s[i], length(s), pos(s), copy(),
delete(), ...) work like expected and introduce new functions for the
work on subcodes. This would allow for creating the same code as it does
with the actual new stuff, while preserving the compatibility to old
school coding style and making porting software a lot easier. You _can_
additionally modify the code if you want to optimize the unicode-enabled
version of your software for speed.
