If you have a Unicode path, and are sending it to a function that takes 
only strings, you generally want to do:

  path.encode(sys.getfilesystemencoding())

which do the right thing to encode the path into something the low-level 
C "fopen" can understand.

One could argue it might be more "Pythonic" for PyCairo to handle that 
conversion internally, but hopefully the above is the correct workaround.
