Good day. I have a dovecot 2.3.4.1 on debian 10 as an imap server. I found there are emails where the header field From has no encoding even if there is a name with special characters like Žlutý Kůň. The header looks like:
From: "Žlutý Kůň" zluty.kun@domain.tld
In this case the email client - roundcube, outlook etc. will show the From with wrong characters. This behaviour is typical only for dovecot, not for courier-imap - it was installed before dovecot with no problems.
If there is corretly encoded From filed, the client shows the From correctly.
Is there a way to set up the dovecot to show the field correctly even without encoding stuff? Some default/fallback settings?
Thank you very much for your help

Is it possible to get a sample mail corpus?

unfortunately im not authorized to publish the whole headers and content, but as an example:
in headers: To: ""Ing. Markéta Kleinová"' x@xxx.xx
view in the webmail or outlook "Ing. Markéta Kleinová" mailto:kleinova@pkvp.cz
and it should be Ing. Markéta Kleinová
The problem is with From and To headers.

Would it be possible at least to provide headers from such mail? Mostly I am interested in what content encodings are specified? You can remove sender/recipient/subject/message-id and such identifying information, but would prefer if you'd leave that ""Ing. Markéta Kleinová"' bit intact.
