How to deal with unicode in strings?

[Gintaras]

QM string encoding is UTF8. It means variable-length characters. Some characters are 1 byte, some 2, 3 or 4 (rarely).
When you know character length, simply use it in code.

Code:

str s="ąbc" ;;first character is 2 bytes
str bad.left(s 1) ;;gets half of character
out bad
str good.left(s 2)
out good

In other cases usually you use find or findrx or similar function to find a substring, and it gives correct result.
