Inverse characters are the same as the characters above with 128
added to the values listed. This is done by setting the seventh bit
(adding 128).
There are other codes used which are outside this range:

ATASCII   Function
155       End Of Line (Return)
156       Delete line
157       Insert line
158       CTRL-Tab
159       Shift-Tab
253       CTRL-2 (buzzer)
254       Delete character
255       Insert character

See your Atari Reference Manual, pages C1 to C3 and F1. In order
to print the arrow keys, clear, insert, delete, buzzer, escape key, or
any of the codes listed above to the screen, you must press the
ESC key before entering the keyboard character(s).

Not all of these codes can be sent to the printer. ATASCII codes
zero to 31 print blank or they may send control codes to your
printer, depending on the make. 96 will print a backwards
apostrophe instead of a diamond, 123 will print a left bracket
instead of a spade, 125 will print a right bracket instead of a clear,
126 will print a tildis instead of a backspace and 127 will print a
blank instead of tab.

There is a third set of codes used by the Atari keyboard handler.
These values are listed in the OS User's Manual.
