Patches to make this customizable will be welcome, I think.  We
already allow customization for the EOL indication.

But please keep in mind that an Emacs buffer doesn't only show files,
it also shows text from other sources.  For example, email, where
Unicode is not as common as files on certain platforms.  And even with
files, don't you see "-" there many times?  If not, it means you are
looking at ELisp files too much ;-)

No, the most typical is to have "-" there, not U.  As long as you deal
mainly with ASCII files, that is.

That indicator has very little to do with the buffer being modified,
so no, that will make little sense.  Moreover, having the indicator
pop up suddenly will attract attention and distract for no good
reason.
