How to get correctly encoded headers (eg =?us-ascii?Q?=3D=3Fiso-8?= =?us-ascii?Q?859-1=3FQ=3F=3DE9=3D29=3D3F=3F=3D?=

[Erwan David]

My gnus dos not want to correctly encode non ASCII characters in the
headers, How can I do it ?

Here is the (I think) relevant part of my configuration

(setq mm-coding-system-priorities
'(iso-8859-1 iso-8859-15 utf-8))

(add-to-list 'mm-body-charset-encoding-alist '(iso-8859-15 . 8bit))
(add-to-list 'mm-body-charset-encoding-alist '(iso-8859-1 . 8bit))

(add-to-list 'mm-charset-synonym-alist '(iso\ 8859-15 . iso-8859-15))
(add-to-list 'rfc2047-charset-encoding-alist '(utf-8 . Q))

(add-hook 'message-header-hook 'rfc2047-encode-message-header)

And it does not work (See the header...)

My message buffer is in UTF-8 (U:**- at the left of the mode line).
