What UNIX programs are you aware of that have major problems with 8 bit
character sets? One that comes quickly to mind is the Bourne shell,
which uses the 8th bit as a tag. I suspect that vi/ex will also have
problems. This would be a good forum to itemize the programs, the
problems and the solutions that can be used as work-arounds.

In the case of path names, the UNIX kernel refuses to accept and 8 bit character set. System Vr2 returns EFAULT if an attempt is made to create a file whose name contains a character with the high bit set. 4.2 BSD returns an EINVAL in the same case.

I'm pretty sure emacs (pick a version) expects that it will be able to use the 8th bit to represent meta-characters. Actually, emacs uses a 9-bit character set (so you can have such things as Control-Meta-Return). I have no idea what all the ramifications of this will be, but I suspect it might get messy. I can see it now -- Joe Emacshacker swoops down on an unsuspecting luser and floors him with "Hey, there's a better way to do that. You can save 2 keystrokes by just doing Control-Top-Meta-Danish_O_Umlaut!" :-) -- Roy Smith <allegra!phri!roy> System Administrator, Public Health Research Institute 455 First Avenue, New York, NY 10016
