How to read a letter if it is encoded in unknown what?

Question

Outlook

Good afternoon, forum users!
The problem arose, a letter arrived, it is displayed correctly and readably on the phone, on the computer it is the same, it gives out ��������� ��������� ���������� ���� ��!
I tried many online decoders, the encoding function built into Outlook, attempts are in vain.
Help, who can meet?
