are talking about changes in C as of C11.

The subject line comes from a commit to Emacs master that added coding-cookie lines like the following to some .el files that had UTF-8 text:

  ;; Local Variables:
  ;; coding: utf-8
  ;; End:

Lines like these are no longer needed with current Emacs, which prefers UTF-8 for .el files regardless of the system locale. This can be a win, as people often forget to insert coding cookies and the cookies are a bit awkward anyway.

The discussion has morphed into the possibility of a similar facility for files other than .el files, and what the defaults for such a facility should be. The idea is to somehow avoid the need for UTF-8 coding cookies for users who prefer Emacs to default to UTF-8 for text files regardless of system locale.
