Subject: bug#26396: 25.1; char-displayable-p on a latin1 tty
Date: Sat, 08 Apr 2017 12:20:57 +1000

On a latin1 tty, char-displayable-p claims that almost all chars are
displayable, eg (char-displayable-p #x2022) => t.

I hoped when (terminal-coding-system) is iso-latin-1-unix that
char-displayable-p would say only relevant latin1 chars are displayable.

I believe this is how it was in emacs24 was (and which helped avoid a
lot of very unattractive \ display escaping, at least from code knowing
not to try to display the undisplayable).
