As we have now a pseudo-UnicodeData.txt for the PUA > characters (at least thise I'm interested in) this doesn't seem to me a > big problem). I think we are miscommunicating. The problems I alluded to start from the fact that we exclude the PUA codepoints from the character property database. This means you cannot change their case and access their syntax category, for example. Functions that select a suitable font also ignore PUA codepoints, IIRC. Etc. etc. -- Someone™ should go over all the places where we specify character properties and use them, and make sure PUA codepoints aren't disregarded. Otherwise, just making Emacs know the names of these codepoints will be of very limited value.
