I don't know for sure but maybe it doesn't support all ASCII escapes
codes.

Why do you care about \b anyway :-) ?

Hi,

I need this inevitable for my "programming language", for code
indentation. I don't know how to write script with module tokenize
for code indentation.

Still not giving up reinventing the wheel? You should take some lessons on
syntax analysis before attempting this. But I know this words won't be
heard...

So, to your actual problem: that backspace is removing a character is
something an editor or a terminal do, because they interpret the backspace.
You wouldn't expect the string "<font color="blue">foo</font>" to be
rendered blue by magic as well, wouldn't you?

So what you need to do is: search the string for backspaces, and remove the
BS as well as the character before. Something along these lines (untested):

teststring = "abc\bcde\b"

while teststring.find("\b") > -1:
pos = teststring.find("\b")
teststring = teststring[:pos-1] + teststring[pos+1:]
