+1 for adding .has_pending_data() stuff. But it'll need a way to
flush pending data out for encodings where incomplete sequence not
always invalid. <wink> This is true for JIS X 0213 encodings.
>>> u'\u00e6'.encode('euc-jisx0213')
'\xa9\xdc'
>>> u'\u3000'.encode('euc-jisx0213')
'\xa1\xa1'
>>> u'\u00e6\u0300'.encode('euc-jisx0213')
'\xab\xc4'
