I tested pine and gnus:

pine creates:

Subject: Re: [Test] =3D?ISO-8859-1?Q?test_de_deboguage_des_=3DE9_et_=3DE8=
 ?=3D =3D?ISO-8859-1?Q?_header_subject?=3D

which seems delivered unchanged by Mailman:

Subject: Re: [Test] =3D?ISO-8859-1?Q?test_de_deboguage_des_=3DE9_et_=3DE8=
 ?=3D =3D?ISO-8859-1?Q?_header_subject?=3D

gnus creates (if configured to strip list-identifiers) :

Subject: Re: test de deboguage des =3D?iso-8859-1?q?=3DE9?=3D et
 =3D?iso-8859-1?q?=3DE8?=3D dans le header subject

which when delivered by mailman becomes

Subject: [Test] Re: test de deboguage des =3D?iso-8859-1?q?=3DE9?=3D et
 =3D?iso-8859-1?q?=3DE8?=3D dans le header subject

this seems the right thing to do also for latin-1 or other encodings ,
is there any chance of getting it integrated to the mainstream
mailman? But I have no idea of the complexity of the task.
