While I agree that example would just be at most an approximation of
what we need, I am interested in what other cases don't work besides
'+', which is arguably a fairly corner case.

Yes, in particular, I think we should use common cases to guide the
definition. For 1. that's an English word with hyphen (and was already
addressed recently). For 2. that's 1) an ideograph followed by an
ideographic punctuation 2) an English letter followed by "," 3) an
English word with "'". For 2., The current definition is already good
enough for the cases (assuming "letter" means [L*] and [N*]) and I am
simply raising another option but I don't have strong opinion in either
way. In any case, please link "letter" to that definition.
