Exception Type: DatabaseError at /deals/share/
Exception Value: ERREUR:  séquence d'octets invalide pour l'encodage « UTF8 » : 0xe9e9e9
HINT:  Cette erreur peut aussi survenir si la séquence d'octets ne correspond pas
au jeu de caractères attendu par le serveur, le jeu étant contrôlé par
« client_encoding ».

Basically it says that the encoding was not valid for UTF8 and contained   0xe9e9e9

这看起来很奇怪，

关于它可能来自哪里的任何提示？

【问题讨论】：

您是否检查过哪些字符作为电子邮件地址提交？

是的，如果我删除身体一切都很好

【参考方案1】：

U+00E9 是带有锐音的拉丁文小写字母 E。

这可能是问题的根源（不一定是原因）：'title':u"éééààà",。

原因可能类似于your_title.encode('latin1').decode('utf8')（当然不是一步）。
