The names come from the Unicode character database (UCD) that is
processed into a bunch of Emacs Lisp files and then preloaded into
Emacs. The version of the Unicode database built into Emacs
determines which codepoints have names and which don't.

If that data is not in the UCD, Emacs cannot know it, unless someone
adds it to Emacs.
