protect_utf8 is a function decorator that can prevent naive

If the wrapped function takes a string, and that string happens to be valid
UTF-8, convert it to a unicode object and call the wrapped function. If a
conversion was done and if a unicode object was returned, convert it back
to a UTF-8 string.
The wrapped function should take a string as its first parameter and it may
return an object of the same type. Anything else is optional. For
example:
def truncate(s):
return s[:1]
Pass "encoding" if you want to protect something other than UTF-8.
