Foreign characters in file causes FunctionClauseError in Dogma.

[Gyllsdorff]

If a file have a ÅÄÖ character Dogma crashes with a FunctionClauseError error:

> mix dogma --strict
** (FunctionClauseError) no function clause matching in Dogma.Util.ScriptStrings.parse_code/2
    lib/dogma/util/script_strings.ex:18: Dogma.Util.ScriptStrings.parse_code(<<229, 10, 32, 32, 32, 32, 116, 101, 115, 116, 32, 34, 102, 111, 111, 34, 44, 32, 100, 111, 58, 32, 97, 115, 115, 101, 114, 116, 32, 34, 97, 34, 32, 61, 61, 32, 34, 229, 34, 10, 101, 110, 100, 10>>, "defmodule FooTester do\n    use ExUnit.Case, async: true\n\n    # ")

This test causes a crash on two points, the comment and the right side of the match. Replace the å with a a and everything works as it should.

defmodule FooTester do
    use ExUnit.Case, async: true

    # å
    test "foo", do: assert "a" == "å"
end

This test does not cause a crash.

defmodule FooTester do
    use ExUnit.Case, async: true

    test "foo", do: assert "a" == "a"
end

The files uses UTF-8 encoding. Erlang and Elixir information:

Hey! Thanks for the report :)

Could you do me a favour and try this with Dogma master please? I think this may have been fixed.

[Gyllsdorff]

It works on the master branch. Good work.

[Louis Pilfold]

Great! I'll release a new version where I can get to a computer.

[Louis Pilfold]

New version released :)
