https://datatracker.ietf.org/doc/html/rfc2045 describes this in full. 
The short version, headers are always sent 7bit, but UTF8 in headers is 
encoded without any other indication, no header to say this happened,So 
it's shown as the encoded (ugly) version in mail clients that do not 
understand it and translated to UTF8 in clients that do. The 
content-Transfer-Encoding field applies to the body only.


The fact that your mail client translates UTF8 'ö' to a '?' indicates a 
problem in your client in UTF8 handling. It understands the convention 
but then cannot render it.
