Python / Remove special character from string

Question

I'm writing server side in python.

I noticed that the client sent me one of the parameter like this:

"↵                        tryit1.tar↵                        "

I want to get rid of spaces (and for that I use the replace command), but I also want to get rid of the special character: "↵".

How can I get rid of this character (and other weird characters, which are not -,_,*,.) using python command?

A regex would be good here:

re.sub('[^a-zA-Z0-9-_*.]', '', my_string)
