Then how to understand this sentence you wrote:
Emacs decodes a specific code point of a specific character set to
an Emacs character.
Under what circumstances does this decoding happen? The only type of
``decoding'' I knew about until now was by decode-coding-region and
friends, which use a coding-system to decode a byte sequence into
Emacs characters.
