Unicode Character 'BULLET' (U+2022)

Thanks for the clarification about unicode.

Concerning escaping the punctuation, good catch!

I had a look to the current spec. In Section 2, it says

A punctuation character is an ASCII punctuation character or anything in the Unicode classes Pc, Pd, Pe, Pf, Pi, Po, or Ps

Then I found out, that the bullet character is in the class Po as defined in this source:

The question for me is why section 2 includes so many Unicode characters in the definition of punctuation characters and then it is explicit about ASCII punctuation characters in section 6.1 as you have already quoted.
