Special caracters display

Some special caracters are not displayed correctly, example “ý” is displayed as “x”

Hi and thanks for your message.

Where do you see this problem – in email messages, or in the list? Could you provide a screenshot (after removing any identifiable information)?

Hello Geir,
I uploaded the requested screenshot. Seems that only the Subjects (list and in header) are affected.

Thank you for taking care!!

Hello Geir,
forget the issue with the special caracters.

There is only one address which sends me emails with the distorted caracters.
Most probably they have some crazy settings on their machine.

BTW: Merry Christmas!
