Thanks very much for your reply.
What I mean is that I would like to use the ascii number in a regular
For instance, if I want to substitute the occurrences of character 'a' for
the character 'b' in a string, instead of doing this:
I'd like to specify the ascii number of a (which is 97)
I tried converting 97 to hexadecimal (with hex()) and tried this
but it doesnt work.
I need this because I'm working on non printable characters.
Thanks a lot
