in reply to Re^7: How to reverse a (Unicode) string
in thread How to reverse a (Unicode) string

Yes it is about Unicode. "Unicode" is in the subject.

Sorry for not setting the subject correctly. Fixed.

Every time it reverses a Unicode string, it performs a Unicode operation.

We've both said that it doesn't. At issue is whether it should. I would like it to, but I'm not sure it's possible.

What kind of operation is this Perl code performing?

A substitution based on a Unicode property match.

Not a Unicode operation?

I agree that it is. substr, length and reverse are not, though.
