This method is called from the
response object. It returns 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 retrieve the character set from the response. To set the character set, see
var char_set = response.getCharacterSet()
This method returns a string value that provides the HTTP response character set.
