SPECIAL CHARACTER PRINTING

ESC I n	Printable Code Area Expansion: If n is binary or ASCII one, some
	ASCII codes between 0-31, and some or all codes between 128-159
	inclusive, become printable as characters. If ESC 6 has been sent
	prior to this command, then all of the characters between 128 and
	159 inclusive are printable. These characters come from the
	international character substitution set.
	Not all control codes between 0 and 31 inclusive can be made
	printable because if the ESC code became printable. For example, no
	more escape commands could be received. If the parameter n is
	binary or ASCII zero, these codes return to the non-printable state.
	Following is a chart showing an executed code between 0 and 31 and
	between 128 and 159 inclusive. If a control code can never be made
	into a printable character, the standard symbol for the code is
	printed instead of its ASCII number. To the right of these codes is the
	name of the character that is printed. Note that this chart assumes
	that an ESC 6 command has already been received and that the
	italics mode has been selected (via ESC t or emulation option 2) for
	the upper section of the table (range 128-255). Otherwise,
	control codes such as FF, CR etc. would be executed in the region
	128-159 inclusive instead of printing an international character. This
	sequence causes some ASCII codes between 0-31, and some or all
	codes between 128-159 inclusive, to become printable as characters
	when n is 1. When n is 0, these ASCII codes are non-printing
	characters.
