| The correct way to use them is to not use them and use
| encode/decode-coding-string instead.

| Don't use them, period. They are remnants from the era long gone,
| before Emacs used Unicode and UTF-8 as the basis for its internal
| representation of characters. Nowadays the only place where such
| conversions are sometimes needed are on the C level, deep within Emacs
| internals. Applications should never use them.
