| Hi!

| I have noticed that latin 1 (or rather non US ascii) characters are mapped
| to 3-strings starting with = character when messages are shown in the
| Mailman archive. For example,

| õ -> =F5
| Õ -> =D5
| ä -> =E4
| Ä -> =C4
| ö -> =F6
| Ö -> =D6
| ü -> =FC
| Ü -> =DC
| \t -> =09

actually it is not mailman that does this, it is the sender. some mail
user agents escape all non-ascii characters this way, even though
practically all non-8-bit-clean mail software has disappeared from the
face of the earth by now.

the archive part of mailman does not know how to decode this
encoding (it is called "quoted-printable", also often called
"quoted-unreadable" :) ).

i guess mailman will have to be taught how to cope with this.  you
could also use some other web archiving software. i have good
experience with mhonarc. (it is nicer in some other respects too.)

the quopri module in the standard library may help you if you
decide to tackle this yourself.
