+A few notes apply to the table itself:
+.bP
+X/Open Curses incorrectly states that the mapping for \fIlantern\fP is
+uppercase \*(``I\*('' although Unix implementations use the
+lowercase \*(``i\*('' mapping.
+.bP
+The DEC VT100 implemented graphics using the alternate character set
+feature, temporarily switching \fImodes\fP and sending characters
+in the range 0x60 (96) to 0x7e (126)
+(the \fBacsc Value\fP column in the table).
+.bP
+The AT&T terminal added graphics characters outside that range.
+.IP
+Some of the characters within the range do not match the VT100;
+presumably they were used in the AT&T terminal:
+\fIboard of squares\fP replaces the VT100 \fInewline\fP symbol, while
+\fIlantern symbol\fP replaces the VT100 \fIvertical tab\fP symbol.
+The other VT100 symbols for control characters (\fIhorizontal tab\fP,
+\fIcarriage return\fP and \fIline-feed\fP) are not (re)used in curses.
