• Unicode chars are ignored as enum values #9411

Start with the supplied OpenAPI declaration and run openapi-generator generate -i swagger.json -g typescript-axios -o typescript-axios to reproduce the generated enum. Compare the output with the expected enum containing the Unicode names; done means the generated TypeScript enum preserves those names instead of emitting blank identifiers.
