Email character set conversion in procmail

[Paul Howarth <paul@xxxxxxxxxxxx>]

Does anyone have a procmail recipe for email character set conversion? I 
help to run an email newsletter, where people send in contributions that 
get edited together into a single message that is then sent out to all 
the list members. It would be nice if all of the incoming messages were 
in the same character set (e.g. utf8, iso-8859-1, whatever) from the 
point of view of pasting them into a single document, but I haven't been 
able to find a recipe for doing this automatically. Any suggestions?

Paul.
