Я использую приложение Python с открытым исходным кодом веб-службы для отправки электронной почты через GAE, но если имя или тело письма содержат арабские или ивритские символы, приложение выдает некоторые ошибки (например, «Указанные параметры недействительны»). Поэтому мне нужно знать, как решить эту проблему. Я должен отметить, что я новичок в Python (одна неделя с тех пор, как я начал играть с Python).
