Hi,

Thanks for the report. I'm not 100% sure, but it seems that it is
because you are compiling ccplot in a directory which contains unicode
characters in its path.

The bug has already been reported to cython, but they don't seem to have
done anything about it.

https://groups.google.com/forum/#!searchin/cython-users/unicodedecodeerror/cython-users/D8_mhkAUZXA/0ALSNrC7iMkJ

I suggest you try moving the ccplot directory to a different system
path, one which does not contain non-ASCII characters. If it does not
help, please let me know.

Regards,

Peter
