The '?' operator returns the ascii code of the character

I think this is evaluated as "\8" and "4". "\x" returns "x" so "84"
makes sense.

Note: there is no decimal substitution only "\nnn" (octal) and "\xnn"
(hex).

This matches the octal form a substitution so it is correct.

> => "T84"

As previously shown the first part matches the octal substitution
"\124" => "T". The second part matches "\8" + "4" => "84". Thus "T84"
is correct.
