Github returns “Problems parsing JSON” when trying to create issue which contains Chinese character
<p>I'm attempting to create an issue on github using curl. 
If there is any Chinese character exist in the json, it always returns "Problems parsing JSON". 
<code>
curl -i -H 'Authorization: token xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' \
   -d '{ \
        "title": "sfsd", \
        "body": "We should have one", \
        "labels": ["中文"] \
      }' \
