Hello, At this point, changing the naming rules of the specification would be a pretty significant breaking change, and I don't think it's likely to happen without a compelling champion that feels strongly about the issue! As far as I know, this is
Using non-compliant names *might* work with some implementations, but there's no guarantee that that schema would be interoperable between Avro versions and languages. This is true regardless of how the schema was generated, unfortunately, including from Avro IDL... I don't believe that the AVDL example above would interoperate with the Python SDK. In my experience, the usual reason I've encountered for wanting to have unicode identifiers is have better, language-specific names or fields like "prénom". As an alternative, in practice, this can be accomplished by adding your own custom JSON property to the type or field name, like "label" or "display.name" (or by reusing the "doc" field) for the human-readable internationalized name. This technique has the advantage, as well, of potentially supporting multiple languages with different properties, or allowing you to rename the field without affecting the canonical schema. The disadvantage is that none of this is provided for you... Is there a specific use case that you're looking to support?
