I learnt that one of the Terminal window settings, under "emulation" and on by default in current Panther Terminal, sends outside-ASCII characters as combinations of ^V and some other character. In the ..plist file the <key> is something like UseCtrlVEscapes. The English label for the setting is accurate: "Escape non-ASCII ...". The Finnish confused me: it translates as "Enable non-ASCII ...", but between the computers that I use, it disables non-ASCII, making local and remote Bash and Emacs just beep at me; they don't seem to expect these ^V-escapes. Does "Enable non-ASCII ..." make sense to somebody? What programs, protocols, systems use ^V this way? Hm, actually, why is this option there at all, and why is it on by default?
