There is a character in the terminfo/curses alternate character set, ACS_LANTERN, which is mapped to "i" in the VT100 alternate grapical character set. This character is, in fact, on a real VT100/VT220 (and therefore in most modern terminal emulators that support the full ACS), "VT" (in 'control character picture' format, along with HT FF CR LF NL). The ASCII mapping uses "#", and some CP437/etc mappings map it to the double box drawing intersection character. Was there ever a real 'lantern' character? The manpage mentions "some characters from the AT&T 4410v1 added". What did it look like?
