Yes I understand this, so it is how Unicode defines joiners. Yeah, debates about the classifications can be hold forever, but one should not forget about the hyphen during these debates. Hyphen is used I think more then six hundreds years as a joiner (or probably some other classification term one prefer). And just comes so it works very well. Among Unicode joiners, middledot reminds of hyphen, but it is not used in typography for this task. So it is not good option and has issues in most fonts (too small or not aligned with lowercase). Often it is used to show up whitespace in editors, so it is kind of 'reserved'. Other joiners in unicode classification - well probably ok for a 1st April proposal. About importance, it was already covered in the proposal. Why it is SO important? It is rhetorical question. Important compared to what? Compared to the question, what one will eat and where sleep tomorrow? Then it is not so important. Mikhail -- https://mail.python.org/mailman/listinfo/python-list
