  # mime decode for ruby 1.9
  def mime_decode( input, out_charset = 'utf-8' )
    while input.sub!(/(=\?[A-Za-z0-9_-]+\?[BQbq]\?[^\?]+\?=)(?:(?:\r\n)?[\s\t])+(=\?[A-Za-z0-9_-]+\?[BQbq]\?[^\?]+\?=)/, '\1\2')

    begin
      ret = input.sub!( /=\?([A-Za-z0-9_-]+)\?([BQbq])\?([^\?]+)\?=/ ) {
        charset = $1
        enc = $2.upcase
        word = $3
        word = word.unpack( { "B"=>"m*", "Q"=>"M*" }[enc] ).first
        # Iconv.conv( out_charset + "//IGNORE", charset, word )
        word.encode( out_charset, charset, :undef=>:replace, :invalid=>:replace )
      }
      return ret ? mime_decode( input ) : input
    rescue
      # "Error while convert MIME string."
      return input
    end
  end

You just saved my life. Isn't there a gem or something to do that in a better way?

Thanks anyway !

Wow, thanks a lot! This is the only thing I could find to help me decode mime encoded subjects from Gmail.
