I collect emails from the IMAP server with the code below, but the content of the email body is often very ugly and sometimes impossible to understand. Many of the letters contain special characters from Denmark and Sweden, such as æ, ä, ö, ø and å, but I do not think this is a problem. What is the best way to encode and clear?
imap = Net::IMAP.new(address, port, enable_ssl?) imap.login(user_name, password) imap.examine(flag) search_query = "#{last_uid}:*" imap.uid_search(search_query).each do |uid| if uid.to_i > last_uid.to_i header = imap.uid_fetch(uid, "BODY[HEADER.FIELDS (FROM TO DATE SUBJECT)]")[0].attr["BODY[HEADER.FIELDS (FROM TO DATE SUBJECT)]"] from = Mail.read_from_string(header).from.first to = Mail.read_from_string(header).to.first rescue nil subject = Mail.read_from_string(header).subject date = Mail.read_from_string(header).date body = imap.uid_fetch(uid, "BODY[TEXT]")[0].attr["BODY[TEXT]"].gsub(/\r\n?/, "\n").force_encoding('UTF-8') end end imap.logout() imap.disconnect()
