I have several workflows which send email notifications. Some of the outgoing emails have very strange titles, like the following:
Скоро срок СЃдачи поручРµния СоздатСЊ расписаниРµ по дисциплинам
Задачи - Настроить работу блога на =?utf-8?Q?=D0=BA=D0=BE=D1=80=
Both sentences are utf-8 encoded, in russian. Some of the characters inside the sentence were replaced with incorrect ones, I have no idea what is the reason of it. Is there any way to investigate or fix it?
