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.
