These should be enormously rare, I think. By and large, we are mostly concerned 
with representing ~/, right? I think it is reasonable to only support (encoded) 
Unicode file paths and not support *completely* arbitrary file paths. I doubt we 
will get a single bug report.

Also, perhaps it's not worth noting, but OS X appears to require UTF-8 encoding 
of filenames. I.e., one should use unicode strings in Python to represent them.
