This is unrelated: it specifies which character sequences should be
composed and displayed as a single grapheme cluster.

You cannot base encoding decisions on the language or script alone,
unless that language exists in a single locale. Many languages and
scripts serve several different locales with several different default
encodings.

Again unrelated. Input methods are about typing characters not
directly supported by the user's keyboard.
