The purposes of mainstream text editing.

(XeLa)TeX is still a very good typesetting system and Emacs-based > AUCTeX is still a very good tool to use TeX. Those are separate projects. If they need to use non-standard characters with corresponding non-standard fonts, they could maintain some add-on packages for Emacs to do that. Asking Emacs to maintain compatibility to various ad-hoc registries outside of Unicode is not really reasonable. How will we know which PUA codepoints to support? How would we know which registered codepoints are stable enough and wide-spread enough to justify their support in Emacs? How will we keep track of the changes in these areas? This is a task for someone who is an expert in this domain, is aware of all the important developments there, and who can update Emacs whenever something important changes. As things are, we have trouble even tracking the Unicode Standard: each new edition takes several hours to incorporate, run the tests, make the necessary changes, etc. I guess what I'm saying is that without a dedicated volunteer who would take care of this issue we can only wish such support will be added, but we have no real hope it will materialize, except by some enormous luck. Of course, if you know someone who could be persuaded to come on board and work on this now and in the future, I think the feature will be welcome. Thanks.
