Rails - Oct 2009 - invalid multibyte character error

Hi.

When I try to use multibyte characters in my rails controller I get an
invalid multibyte characters error
(<rails_app>/app/controllers/admin_controller.rb:6: invalid multibyte
char (US-ASCII)).

Here is my controller:

contoller AdminController < ApplicationController
  def read
    @title = ''Заголовок страницы''
  end
end

Here is my haml template extraction:

...
%title= @title
...

After I start the WEBrick server and go to
http://localhost:3000/admin/read I get the error. However, if I set #
encoding: utf-8 on top of the controller file the error disappear.

The question is how can I "officially" correct this error? How can I
maintain Rails to proper multibyte characters handling?

Is there a solution to this in 2010?

Self-reply: is there a solution to this in 2011?

I am running Rails 3.0.3 with Ruby 1.9.2 and it still fucks up.

I see this:

$ ruby -e ''puts Encoding.find("locale")''
ASCII-8BIT

How to set the proper locale/encoding?

From that url: 
http://nuclearsquid.com/writings/ruby-1-9-what-s-new-what-s-changed.html

"Ruby 1.9 can now properly read source code files encoded in formats 
other than ASCII, as long as you declare it:

# coding: utf-8"


Don''t tell me I have to put that in every file of my apps?

Some more configuration to escape error:

    - Make sure ''config.encoding = "utf-8"'' is there
in application.rb
file.
    - Make sure you are using ''mysql2'' gem
    - Putting ''# encoding: utf-8'' on top of rake file.
    - Above ''<AppName>::Application.initialize!'' line in
environment.rb
file, add following two lines:

    Encoding.default_external = Encoding::UTF_8
    Encoding.default_internal = Encoding::UTF_8
