Thanks, this looks right. I guess this is how we need to iterate over unicode
now.
Btw, why isn't there a for-loop we can use over unicode strings? seems like
that should be supported out of the box. I had this same problem in Swift also
where it's extremely confusing to merely iterate over a string and look at each
character. Replacing characters will be tricky also so we need some good
library functions.
Swift is especially terrible because there's NO ANSII string so even a 1 byte
sequence needs all these confusing as hell functions to do any work with
strings at all. Terrible experience and slooooow.
