Swagger to typescript enum property name issue

[johnnyzh82]

I use nswag to generate typescript model from swagger json. I found an issue when enum string contains invalid characters which are unable to map to enum keys.

"enum": [
     "Test1",
     "Test2",
     "Test1,Test2",
],

And result of typescript model doesn't transpile to js due to an invalid key in enum property (has comma in this case).

export enum MyEnum{
    Test1= "Test1",
    Test2= "Test2",
    Test1,Test2= "Test1,Test2",
}

The typescript version I use is 3.2 and nswag version is 12.0.15.

Thanks
