[Bug 1672479] [NEW] Nova servers APIs respond with Unciode ignoring charset in request headers

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

GET ‘servers’ API responds with \u escaped Unicode characters even though the request headers specify that the client will only accept UTF-8 encdoding.
                                
Both these headers were tried, with same result : “Accept: application/json;charset=UTF-8”   and “Accept-Charset: UTF-8”
