Wikipedia states that D still has some Unicode problems:

characters)."
Is this information correct?
They're not bugs, if that's what you mean. It's just a side-effect of
how Unicode works.

Long story short: they operate on bytes because operating on actual code
points can't be done efficiently [1].

[1] Given that strings are implemented as arrays with a given,
non-changing width and that you're not using UTF-32 which no one does
because it's too big and that we don't add some fancy caching stuff to
char[] arrays specifically, blah blah blah.
I use UTF-32, at least occasionally. In cases where I specifically
expect/encourage multilingual support/use, it can simplify matters
greatly, where those otherwise inefficient operations become common.
