1. Create test pod in which Chinese character along with some other special character will be printed

$ oc new-project test
$ oc new-app https://raw.githubusercontent.com/openshift/verification-tests/master/testdata/logging/loggen/container_json_unicode_log_template.json
$ POD=$(oc get pods -o json | jq -r .items[0].metadata.name)
$ oc logs -f $POD

2. Access API server via 

$ oc proxy
$ xdg-open http://localhost:8001/api/v1/namespaces/test/pods/$POD/log?container=centos-logtest

3. Notice that response header Content-Type does not have utf-8 encoding as needed for proper decoding of the content. This results in the log content appearing distorted.

    Content-Type HTTP header is text/plain

    Content-Type HTTP header should return text/plain;charset=[charset] depending on what charset the pod is using (likely utf-8)
