On Unix, any function is exported in a shared library by default, but the behavior is the opposite on windows, where a function without it will not be visible from external code.

Re: [matplotlib-devel] [Matplotlib-users] encoding of files included in sphinx
Hi,
just wanted to raise this problem on the devel list, where it probably
belongs. Also, if nobody has time to look at it now and you prefer me to
file a bug, please don't hesitate to tell it.
the original post is there:

Cheers

I ended up implementing this myself, it wasn't too hard. I've attached
the code if anyone else is interested. I don't know matplotlib that
well, so I don't know if there's much duplication of code in there.
I thought I'd CC the dev list in case others think it might be useful.
If not, sorry for the noise.
Cheers,
Jason
