Yes. ISO-2022 = ECMA-35
search in www.ecma.ch for ecma-35.pdf

Dear Unicoders,
again, I have inadvertently sent a contribution to a member rather than
to the whole list, because the Unicode list sets the Reply-to header in

Now I have a much clearer understanding of the reasons behind controls 0x7F
and 0x08 (DELETE and BACKSPACE). First of all, their names now makes more
