Question

我正在使用IMAPClient库，但在进行搜索时我得到UnicodeEncodeError。下面是一个片段和堆栈跟踪：

imap_client = imapclient.IMAPClient('imap.gmail.com', use_uid=True, ssl=True)
imap_client.oauth2_login('john@example.com', 'xxx')
subject = u'Test \u0153\u2211\u00b4\u00e5\u00df\u2202'
from_email = u'john@example.com'
to_emails = [u'foo@example.com']
cc_emails = []
approx_date_sent = '05-Aug-2013'

imap_client.select_folder(r'\Sent')
search_criteria = [
   u'FROM %s' % from_email,
   u'SUBJECT %s'.encode('utf-8') % subject,
   u'TO %s' % ';'.join(to_emails) or '',
   u'CC %s' % ';'.join(cc_emails) or '',
   u'SENTON %s' % approx_date_sent
]
msg_ids = imap_client.search(search_criteria, charset='utf-8')

'ascii' codec can't encode characters in position 77-82: ordinal not in range(128)

问题似乎发生在ssl.py？ ssl=True需要oauth2_login。
