The following patches enable RFC1342 compatible decoding of header fields
|
||
for non-ascii character sets.
|
||
|
||
Additional tips:
|
||
setenv MM_CHARSET <rfc1342 charset>
|
||
setenv LC_TYPE <proper locale>
|
||
|
||
e.g. setenv MM_CHARSET KOI8-R
|
||
setenv LC_TYPE ru_RU.KOI8-R
|
||
|
||
or setenv MM_CHARSET iso-8859-1
|
||
setenv LC_TYPE iso_8859_1
|
||
|
||
Change your mhl.format to read so that the new code will be invoked on
|
||
interesting fields when you do a "show":
|
||
|
||
From:formatfield="%(comp{text})"
|
||
Reply-To:formatfield="%(comp{text})"
|
||
To:formatfield="%(comp{text})"
|
||
cc:formatfield="%(comp{text})"
