I think this depends on the level at which the digest is processed by 
the recipient. I haven't used digests much, and when I used them, I 
always saw them just as a concatenation of the mails with the relevant 
headers. In that case, they are just plain text, and should work well 
with UTF-8.

Of course, for cases where digests are elaborate multipart constructs, 
and clients and users that want to act on these constructs, that's 
different. I'm not enough of an email expert to know how important this 
kind of use case is.

Regards,    Martin.
