[sylpheed:34714] text/plain attachments are missing charset-declaration

[Ervin Peters]

Hallo,

attaching a plain/text file creates amultipart message with an
attachment header like this:


--------8<-----------
--Multipart=_Mon__15_Aug_2011_18_14_27_+0200_VkWwTjDTaeZI2r8Q
Content-Type: text/plain;
 name="contra-helmpflicht.txt"
Content-Disposition: attachment;
 filename="contra-helmpflicht.txt"
Content-Transfer-Encoding: quoted-printable
--------8<-----------

There is no hint about the used charset. Modern Linux uses utf8, older
latin1 in Europe. Wouldn't it be nice for convenience to have an option
to choose either the system charset, or to be asked which charset should
be set?

to generate an attachment header like this:
--------8<-----------
--Multipart=_Mon__15_Aug_2011_18_14_27_+0200_VkWwTjDTaeZI2r8Q
Content-Type: text/plain; charset=utf8;
...
--------8<-----------
