Due to a bug the was fixed in Python-2.7, in Python-2.6 unicode strings
that are written to sys.stdout (using sys.stdout.write) are not
converted to bytestrings using the file.encoding. Instead
sys.stdout.encoding is set to None, and the default encoding is used. We
solve this by creating a wrapper to stdout, and encoding everything
either with the file encoding, or with the `locale` prefered encoding.
