JSON with Umlaut (äüö) not ok on Python 2.7

I am having the following code:
```
            r =requests.get('http://{}/api/{}/groups/37'.format(HUE_BRIDGE, API_CODE))
            log.info('r.content: {} '.format(r.content))
            log.info('r.headers["content-type"]: {} '.format(r.headers['content-type']))
            log.info('r.json(): {} '.format(r.json()))

```
the log output:

```
2020-03-29 17:10:57.224 [INFO ] [jsr223.jython.huegroups.log         ] - r.headers["content-type"]: application/json; charset=utf-8

```
One of the values is **T\xe4st Gruppe** instead of **T\xe4st Gruppe** is delivered

Running the same request from the Chrome REST Client:
```
{"action":{"bri":74,"colormode":"ct","ct":370,"effect":"none","hue":0,"on":false,"sat":127,"scene":"3","xy":[0,0]},"devicemembership":[],"etag":"b5e003450e01af7f862214ded33c74b6","id":"37","lights":["17","2","6"],"name":"Täst Gruppe","scenes":[{"id":"1","lightcount":3,"name":"Morning","transitiontime":10},{"id":"2","lightcount":3,"name":"Evening","transitiontime":10},{"id":"3","lightcount":3,"name":"Middle OFF","transitiontime":10}],"state":{"all_on":false,"any_on":false},"type":"LightGroup"}

```
response headers:
```
access-control-allow-origin: *
content-type: application/json; charset=utf-8
content-length: 498

Made some tests on online python server [python3](https://repl.it/languages/python3) and [python2.7](https://repl.it/languages/python) with sample json [http://my-json-server.typicode.com/lukicsl/requests-issue/posts/1](http://my-json-server.typicode.com/lukicsl/requests-issue/posts/1)

Seems that that's the way how Python 2.7 handles utf-8
