Describe the bug

When I try to create a reverse proxy for the blog with the following response header:

access-control-allow-credentials: true
access-control-allow-origin: *
cache-control: public, max-age=0
content-encoding: gzip
content-type: text/html; charset=utf-8
date: Fri, 25 Sep 2020 10:15:43 GMT
etag: W/"9127-u+4Jv+RfD2erbftmcMqr2DT5eig"
status: 304
strict-transport-security: max-age=315360000; includeSubDomains; preload
vary: Origin
x-powered-by: traefik(made with ❤️ with go)

It throws an expectation, InvalidOperationException: Invalid non-ASCII or control character in header: 0x00E2 in line 698 😂😂😂

To Reproduce

  "ReverseProxy": {
    "Routes": [
      {
        "RouteId": "blog",
        "ClusterId": "blog",
        "Match": {
          "Path": "{**catch-all}"
        }
      }
    ],
    "Clusters": {
      "blog": {
        "Destinations": {
          "blog/destination1": {
            "Address": "https://yunfan.dev/"
          }
        }
      }
    }
  }
