Portions of this patch, but not the Unicode normalization have been applied or otherwise addressed in MM versions 2.1.6 through 2.1.15. I intend to deal with the spirit of the rest by converting the headers to the cset of the list's preferred language using encode(errors='backslashreplace') instead of encode(errors='replace'). In this way, these characters will be converted to '\uxxxx' escapes rather than '?', and header_filter_rules patterns can be constructed to match them. ** Changed in: mailman Importance: Undecided => Low ** Changed in: mailman Status: New => In Progress ** Changed in: mailman Milestone: None => 2.1.23 ** Changed in: mailman Assignee: (unassigned) => Mark Sapiro (msapiro) -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/558155 Title: i18n: Header Filter Rules (& fix) - rules don't match if header characters aren't representable in cset of list's preferred language.
