You're confusing MIME type with the character set, and the encoding of that
character set. The MIME type talks about the document type. The charset and
encoding are about the representation of that document.
It would be quite easy to attach character set and encoding properties.

I would disagree. I think you are/were conflating MIME type with the
character set/encoding issues.

I think that it would always remain text/, since that is the major type of
the document being referenced. The subtype is the question.
But that is neither here nor there. The original question came up with
content-type diff engines. Subversion can certainly retain enough
information to drive a diff engine selection process quite fine.
