[Mailman-i18n] Corrupted foreign fonts.

Hi! In monthly reminders send by mailman in Polish, Polish fonts are corrupted. Code page in the header of the message is correct i.e. iso- 8859-2, but instead of Polish fonts there are only some numbers displayed as can be seen there: http://znik.wbc.lublin.pl/~ak/rozne/bad_PL_fonts.gif What should be done to fix it? Regards Andrzej.
