I just added a few recommendations to CONTRIBUTE about that.

Other than that, we don't have a bug number.  I don't think it's a
bug, more like inconvenient feature: Emacs cannot determine the
encoding of arbitrary text with 100% reliability, so files whose
encoding is not unequivocally determined by their file-name extension
or some other meta-data need a coding cookie to avoid incorrect
decoding.  With UTF-8 encoded files (which is the encoding we prefer
in Emacs), the problem happens in locales whose codeset is not UTF-8,
because Emacs prefers the locale's encoding when no other information
is available.

No, it's very old.

I'm not aware of anyone working on that, nd it's a large and
complicated problem, so the answer is probably yes.
