That's a valid concern. But

| Emacs 21 internal format used in buffer and string.
| Type: emacs-mule (Emacs 21 internal encoding)
| EOL type: Automatic selection from:
| 	[emacs-mule-unix emacs-mule-dos emacs-mule-mac]
| This coding system can encode all emacs-mule charsets.

Would you agree to use utf-8-emacs instead, which covers all characters.
