When an application is displaying header fields to the user, it should
apply ToUnicode to domain labels found in domain name slots.  RFC 822
defines the syntax of every header field, and some of those fields have
<domain> in their definition.  Those <domain>s are the domain name
slots.  Anything else in the header is not a domain name slot.
