Yes, '\x08' is the ASCII code for backspace.  So if you truly wanted to
convert it to ASCII, as your state in your subject, then actually there
is nothing you need to do :-).

You will need to come up with the set of characters that are
(un)/acceptable to you and then strip those out.  I'm not sure what you
mean to just looks like 'Test!'.  If you removed all the backspaces it
would be 's Test!', but if you "played" the string then it would be
'Test!'.  If that's what you want then you need something that "acts
like a terminal emulator" on a string and gives you the resulting
output. The only I can think of that can probably do that for you is
