Regexp pattern not escaped in JSON

[provegard]

I have a property with the following attribute:

[RegularExpression("(?s)^[^\u0000-\u001f\\\\/*?<>|:\"]+$")]

Swashbuckle emits the following JSON:

"pattern": "(?s)^[^�-\\\\/*?<>|:\"]+$",
"type": "string"

Swagger-UI doesn't like this:

I tried NSwag as well, and it outputs:

"type": "string",
"minLength": 1,
"pattern": "(?s)^[^\u0000-\u001f\\\\/*?<>|:\"]+$"

...which Swagger-UI is happy with.
