This method is called from the
response object. It sets the character set for the HTTP response.
When developing server-side functions for applications that interact with OrientDB through the HTTP protocol, you may find it convenient to retrieve or set the character set value on responses, especially if you are using a non-standard character set. Using this method, you can set the character set for the response. To retrieve the character set, see
var res = response.setCharacterSet(<character-set>)
<character-set>Defines the character set for the HTTP response, a string value.
This method returns the updated response object.
