Bug #4249: Net::IMAP gets a parse error response while sending multibyte =
mail
http://redmine.ruby-lang.org/issues/show/4249

Author: Yoshimasa Niwa
Status: Open, Priority: Normal
Category: lib
ruby -v: ruby 1.9.2p136 (2010-12-25 revision 30365) [x86_64-darwin10.6.0]=


RFC3501 which defines IMAP version 4 rev 1 said:

"A literal is a sequence of zero or more octets (including CR and LF), pr=
efix-quoted with an octet count
in the form of an open brace ("{"), the number of octets, close brace ("}=
"), and CRLF."

current imap.rb sends the number of characters not the octet count while =
sending String to server.

def send_literal(str)
  put_string("{" + str.length.to_s + "}" + CRLF)
  ...
end

I've attached the code to reproduce the bug, and a small patch.
if Net::IMAP is designed that it expects ASCII-8BIT String, this may not =
a bug though.
