Description

Sorry, naive windoze user here, so apologies if i'm breaking some etiquette.

I had a problem where users posting emails to our redmine system that embedded certain unicode characters caused the email system to stall - MySQL squeaked about illegal characters and the script aborted, so no emails processed. To overcome the problem I hacked the code as shown below. This worked for us, but I no very little about ruby or rails or redmine internals so don't know if its a 'good' hack and useful to others.

def self.receive(email, options={})
    @@handler_options = options.dup

    @@handler_options[:issue] ||= {}

    if @@handler_options[:allow_override].is_a?(String)
      @@handler_options[:allow_override] = @@handler_options[:allow_override].split(',').collect(&:strip)
    end
    @@handler_options[:allow_override] ||= []
    # Project needs to be overridable if not specified
    @@handler_options[:allow_override] << 'project' unless @@handler_options[:issue].has_key?(:project)
    # Status overridable by default
    @@handler_options[:allow_override] << 'status' unless @@handler_options[:issue].has_key?(:status)

    @@handler_options[:no_account_notice] = (@@handler_options[:no_account_notice].to_s == '1')
    @@handler_options[:no_notification] = (@@handler_options[:no_notification].to_s == '1')
    @@handler_options[:no_permission_check] = (@@handler_options[:no_permission_check].to_s == '1')

    email.force_encoding('ASCII-8BIT') if email.respond_to?(:force_encoding)
    email = email.encode("UTF-8",:invalid=>:replace,:undef=>:replace,:replace=>"?") ##15/12/14 DCN HACK added
    super(email)
  end

Its not quite a duplicate of #16122 in that I want the email to be processed by stripping out illegal characters rather than it just being ignored.

But, the reason is same with #16122.

Your fix in description is wrong.
Mail content is not UTF-8.
For example, source:tags/2.6.0/test/fixtures/mail_handler/japanese_keywords_iso_2022_jp.eml

OK. I was just letting others know I had a problem and this was the fix (for me). I thought it may be helpful. If not, fine. However, I would like the email system to absolutely positively not stop, ever, and not ignore things either.
