    Do we really need these two functions?  I think we have the necessary
    infrastructure in Emacs:

      . find-charset-region

      . find-coding-systems-region
    ...

I don't know whether they do 100% of the job.  I asked Handa basically
that question a week ago, but he has not answered yet.

I have been working on extracting the actually needed parts of mm-util.el.
That code often consists of wrappers around these standard functions.
But it does not have comments explaining why do something different,
or which cases  are intended to get different treatment, etc.
