I think this might be a bug, but I'm not sure. The following code
raises an exception:

 # encoding:utf-8
 
 require 'minitest/autorun'
 
 
 class NewConverterTest < MiniTest::Unit::TestCase
   def setup
     @old_internal = Encoding.default_internal
     @old_external = Encoding.default_external
   end
 
   def teardown
     Encoding.default_internal = @old_internal
     Encoding.default_external = @old_external
   end
 
   def test_iso_8859_utf_8_change_encodings
     Encoding.default_internal = 'UTF-8'
     Encoding.default_external = 'ISO-8859-1'
 
     Encoding::Converter.new 'ISO-8859-1', 'UTF-8' # boom!
   end
 end

Exception:

   1) Error:
 test_iso_8859_utf_8_change_encodings(NewConverterTest):

Is this intentional? If so, why? Thank you.
