Looks great. Thanks for updating the patch!

It would be good to have a test case that demonstrates the discrepancy. Something the following could be add to the test_fixed_size_string method here

avro/lang/ruby/test/test_schema_validator.rb

Line 94 in d94862f

def test_fixed_size_string

assert_failed_validation("at . expected fixed with size 3, got \"a\u2014b\" with size 5") do
  validate!(schema, "a\u2014b")
end
assert_failed_validation("at . expected fixed with size 3, got \"a\u2014b\" with size 5") do
  validate_simple!(schema, "a\u2014b")
end

Thanks for fixing this!

Thanks @tjwp I've added the test.

@Fokko There was an existing test_fixed_size_string method in that test file that contains a couple of assertions. I was suggesting that you add to that existing method. The change you made is overriding the existing test.

I see, thanks for pointing out @tjwp
