non-latin url routing

I'd like to request an ability to handle non-latin url(such as Asian or Arabic language) on routing.
on 3.x, it does not handle those correctly.

You have asked for a CI3 feature in the CI4 subforum? Which are you interested in?
Doesn't CI handle this already, perhaps apart from some escaping issues?

Yes it's escaping related.
I'd like to make a rule using unescaped text but that's not possible on 3.x.
