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 agree with Richard that there should be an option for displaying > characters outside of the current font as "�" rather than "\u2022". 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. > It is a feature of the Linux console that all such characters are > displayed that way. 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! > There is no possibility of any character causing an undefined > action. Famous last words. (And we don't send characters to the console, we send bytes.)
