Well the obvious solution would be ASCII 0x1D (Group Separator)! Accept, no one actually uses those ASCII characters. Kind of bums me out that UNIX basically skipped out on them.
Isn't it? I thought all the separator characters (0x1e, 0x1f, 0x1c) were specifically for delimiting records, fields and units.
What are they for?
I think it’s used to mark sections in Emacs Lisp code.
