Net::IMAP: Encoding problems

[Maik Schmidt]

I've used Net::IMAP for the first time and all in all it worked very
well. But I have one problem: When I download mails containing non-ASCII
characters in the subject or the body, they are encoded using the
q-encoded quoted-printable encoding scheme. How can I convert them to
normal String objects? unpack("M*") does not seem to support q-encoding.

Another question: Is it possible to dump a complete mail received via
Net::IMAP, so that I can feed it into RubyMail or TMail?

Cheers,

Maik

normal String objects? unpack("M*") does not seem to support q-encoding.

def decodeqp(str)
str.gsub(/=\?(.+?)?\?([bq])\?(.+?)\?=/i) { |x|
m = $~
case m[2].downcase # m[2] is type of encoding
when "b" then s=m[3].unpack("m*").to_s # m[3] is encoded string
when "q" then s=m[3].unpack("M*").to_s
end
case m[1].downcase # m[1] is charset
when "iso-8859-1"
...
when "iso-8859-2"
....


you might use iconv for charset conversion then
