Re: Unicode 15

[समीर सिंह Sameer Singh]

admin/notes/unicode says that the zero-width characters are not taken from EastAsianWidth.txt and also

there are some zero width characters defined in that which are not present in the char-width-table in

lisp/international/characters.el, so should I include them there or is there some other location from where

I have to verify the zero width characters?

Thanks.

It is not missing, it is in test/manual/ directory.  See this part of
admin/notes/unicode:

  The file BidiCharacterTest.txt should be copied to the test suite, and
  if its format has changed, the file biditest.el there should be
  modified to follow suit.  If there's trailing whitespace in
  BidiCharacterTest.txt, it should be removed before committing the new
  version.

No, because Emacs doesn't (yet) handle this character as Unicode mandates.

Probably, yes.
