Description

Hello,

we have an issue with processing UTF7 mails:

exception: code converter not found (UTF-7 to UTF-8)
["/srv/redmine/public_html/lib/redmine/codeset_util.rb:25:in `encode'", "/srv/redmine/public_html/lib/redmine/codeset_util.rb:25:in `to_utf8'"

Are there any ideas to solve this issue?

Thx
Falk

It seems Ruby does not have UTF-7 converter.

This encyclopedia article for UTF7 seems to be a good place to start

toshio harita: utf-7 is relevant only for email processing. Ruby still supports it, but it's a little bit tricky. This will work:

require "net/imap" 
Net::IMAP.decode_utf7(mail_body)

The same problem with Windows-1258. Attached patch should cover all not supported code pages.
