Python IMAPClient/imaplib搜索unicode問題

我正在使用IMAPClient庫，但我在搜索時收到UnicodeEncodeError。下面是一個片段，並堆棧跟蹤：Python IMAPClient/imaplib搜索unicode問題

imap_client = imapclient.IMAPClient('imap.gmail.com', use_uid=True, ssl=True) 
imap_client.oauth2_login('[email protected]', 'xxx') 
subject = u'Test \u0153\u2211\u00b4\u00e5\u00df\u2202' 
from_email = u'[email protected]' 
to_emails = [u'[email protected]'] 
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')

似乎問題發生在ssl.py？ oauth2_login需要ssl=True。

哪個IMAPClient的版本您使用的？處理unicode和搜索條件從1.0開始就有了很大的改進。 –

嘗試了這一點

Python IMAP search using a subject encoded with iso-8859-1

它涵蓋了UTF-8和ISO-8859-1

雖然我已經做了同樣的事情？ 'subject = u'Test \ u0153 \ u00b4 \ u00e5 \ u00df \ u2202'' ...'u'SUBJECT％s'.encode（'utf-8'）％subject，'。 – john2x
