Alternative property name extension

Description

If I have an object-schema with properties (culture and invariant culture, see example) and one of the name is * to represent the invariant culture. The C# code generator will strip this character away and make invalid C# code. The stripping off the * is correct because it is not a valid value for a property name on the generated class.

Do it exists any extensions/vendor-extensions tags that I can add to my definition to let the code generator create properties with an alternative name but have the [DataMember(Name="*")] attribute set?

Swagger-codegen version

Using swaggerhub so not sure about exact version number.

Example definition in my yaml file

components:
  schemas:
    Fields.Blocks:
      type: object
      properties:
        _name:
          type: object
          properties:
            en-US:
              $ref: '#/components/schemas/FieldMetadata.Text'
            sv-SE:
              $ref: '#/components/schemas/FieldMetadata.Text'
        _audienceTargetGroups:
          type: object
          properties:
            '*':
              $ref: '#/components/schemas/FieldOption.BlockArea._audienceTargetGroups'

Read the YAML example and trace the C# generator's property-name handling; check the generator's documented vendor-extension support and generated DataMember output. Done means identifying whether an extension can preserve Name="*" while emitting a valid C# property, or documenting that no such support exists.
