Apparently, below this code, you do care that "data" contains
"str" (not "bytes") -- otherwise, you could simply drop this line.

Note, in addition, that the code above might only work if "data" actually
contains ASCII only bytes (at least in Python 2.x, it would fails
otherwise). To safely decode bytes into unicode, you need to precisely
know the encoding -- something which is not consistent with
"I do not care about what data I am working with".
