So you don't like fbterm.  That doesn't mean Richard won't.

The fact that fbterm uses hacks and kludges shouldn't be significant,
since many a software on GNU/Linux does.  Including Emacs, btw.  The
question is: does the user like the end result?

I already explained how to set that up, so what exactly does the
"should be" part here want to say?  There is already such a way in
Emacs.  Just use it, if that's what you want.

That feature provides no way of using it via standard terminfo
interfaces.  Heck, even the way to ask the console which characters it
supports is a kludge specific to that console!

Famous last words.  (And we don't send characters to the console, we
send bytes.)
