> There are cases when we need strings and can't use bytes in python 3.
> We need an utility function for these cases. I agree that this may not
> be the best possible way out. I will be happy if anybody else can suggest
> a better approach. We need this functions for os.path.join(), __slots__
> and few more things. Added the function in pycompat.py as it is not too big
