[PATCH] filter: set environment variable PYTHONIOENCODING to utf-8

[Jason A. Donenfeld]

Hey guys,

Sorry for the delay. I'm currently on the road traveling and won't be
properly back at my desk until the end of next week.

However, my initial reaction is that hard coding various
interpreter-specific environment variables in cgit itself is not
correct, and that this is something better left to the CGI environment
as it sees fit. However, we may benefit from explicit script level
configuration of unicode stuff.

I'll revisit this next week.
