docstrings should be moved out of the C modules, and into resource
files. (possibly via macros and an extractor). when I ship programs
to users, I should be able to decide whether or not to include docstrings
without having to recompile the darn thing.
and yes, docstrings should support any encoding supported by python's

I think the only reason that this hasn't already been done is to reduce the
amount of swearing during the conversion process (both for the core developer
and C extension developers...).
