It depends.

Plain text digests are encoded in Mailman's character set for the list's
preferred_language. For English, this is us-ascii unless you've changed
it. Thus, non-ascii unicodes will be rendered as '?' in the plain digest.

You can change Mailman's character set for English to UTF-8 by putting

add_language('en', 'English (USA)', 'utf-8', 'ltr')

in mm_cfg.py but this has other side effects. Most importantly, the
Python email library encodes utf-8 message bodies as base64. this makes
it difficult to find messages in mailboxes with tools like grep.
