invalid enum names cause duplicates

[quezlatch]

Hi,

say i have an openapi.json files with the following content:

"SomeField": {
  "type": "string",
  "enum": [
    "AB",
    "AB-",
    "AB+",
  ]
}

I will end up with an Enum with two AB_ values. which will cause a compile error. How might I more intelligently interpret the invalid characters - and +?

many thanks!
