How to receive inbound messages with unicode subject?

问题

When I receive message with Unicode subject, I am getting the following error:

'ascii' codec can't decode byte 0xd0 in position 0: ordinal not in range(128)
Traceback (most recent call last):
  File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/webapp/_webapp25.py", line 716, in __call__
    handler.post(*groups)

UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 0: ordinal not in range(128)

The same problem happens with Development environment. Is there any way to fix it?

I see the following in e-mail headers:

Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: 7bit

回答1:

I had to parse e-mail message manually since I haven't found a way to fix this problem - http://code.google.com/p/googleappengine/issues/detail?id=8989

Please see https://stackoverflow.com/a/16129023/604388 to understand how I do it.
