No.  The purpose is to indicate the buffer's file coding system.  You
can put non-latin-1 characters in a buffer with a latin-1 file coding
system just fine.  The file coding system is only relevant when the
buffer contents is saved.

The buffer contents, if multibyte, is always represented by
utf-8-emacs-unix, but that is an internal detail.
