Unicode doesn't have the concept of "syntax", it's our invention. For some syntactic categories, it makes sense to follow the corresponding Unicode general category. Two examples are "punctuation" and "symbols". The question whether to treat Zs as whitespace syntax is on the table. We previously treated many of such characters as "punctuation", which doesn't seem right to me. Which is why I removed them from the "punctuation" syntax, and you got bitten byu the result (because the default syntax is "word-constituent"). > Should the word characters separated by NO-BREAK SPACE by treated as one word? That's a good question. Do we currently treat them as such? I don't think so, because NBSP has the '.' syntax, i.e. "punctuation". > If there is no reason to treat space characters as part of words, then all > characters with the Zs general category could have the same whitespace syntax. I tend to agree. If no objections or new issues arise, I will do that in a couple of days. Thanks.
