c
If
c is a single character, the control character
is set to that character.
In the POSIX locale, if c is preceded by a caret (^)
indicating an escape from the shell and is one of those listed in the
^c column of the following table, then its value used (in the Value
column) is the corresponding control character (for example, ``^d''
is a CTRL-d). ``^?'' is interpreted as DEL and ``^−''
is interpreted as undefined.
