Re: [csswg-drafts] [css-text] U+205F Medium Mathematical Space (MMSP) not mentioned (#3878)

With the specification now clarified, I think we can answer the original question: is U+205F Medium Mathematical Space a word-separator character or not? The answer is no, because it is not a character "whose primary purpose and general usage is to separate words". (it's primary purpose and general use is to separate parts of equations/formulas).

The bit of text listing various fixed sized spaces (but not this one) is clarified to be neither normative nor exhaustive, and merely illustrate that just because something is punctuation or spacing, that doesn't necessarily means it is a word separator. This informative note doesn't change the above conclusion.

Given than unicode is an evolving dataset, we cannot be exhaustive here about which character is or isn't a word separator, as that list would eventually become stale. That's why it is stated in terms of the principle that guides this classification (with a clarifying note), so that the reader can apply it themself.

@briansmith, does that work for you?
