Note that "plain text" should not be used as a synonym for "ASCII
plain text"; UTF-8 files are plain text if they contain a sequence of
characters each used for its ordinary meaning, neither binary nor
markup.

Does anyone actually do anything useful with this part of RFC 2231?

Language-tagging plain text is rarely necessary.  When necessary, it is
rarely sufficient.
