Title: Fix receiving utf-8 characters in media push messages

When receiving a media message via push, that contains unicode characters (e.g. emoji) in the body, the unicode characters are shown as ??.
This is because the received body is converted to a ISO_8859_1 byte array.
I changed it to convert it to a utf-8 byte array and set the encoding appropriately. Then the unicode characters are received correctly.

Message with wrong encoding:
