It seems like there are 2 places where we can put the test. I picked the first one, let me know if there is a better place for testing.

	{
	"latin2" => Encoding::ISO_8859_2,
	"ISO_8859-1" => Encoding::ISO_8859_1,
	"cp-850" => Encoding::CP850,
	"" => Encoding::BINARY
	}.each do |from, to|
	it "should support #{from}" do
	expect { ::Encoding.find(from) }.to raise_error(ArgumentError)
	expect(Mail::Ruby19.pick_encoding(from)).to eq(to)
	end
	end

	it "finds encoding" do
	if RUBY_VERSION >= "1.9"
	expect(Mail::Ruby19.pick_encoding("Windows-1252")).to eq Encoding::Windows_1252
	end
	end
