Reading UTF-16 text file with module 'codecs' fails, if surrogate pair is located at 72-character boundary. Attached python script fails with message: UnicodeDecodeError: 'utf16' codec can't decode bytes in position 70-71: unexpected end of data The reason is splitting of input data for readline() into chunks, namely readsize = size or 72 |

The utf16 incremental codec does not like incomplete surrogate pairs. Patch attached. I also plan to refactor all the test_partial() functions of test_codecs, to give them a common implementation. |
