If you are using a tool such as Postman to perform requests against a Chinese Data Source and are being returned with "???" instead of the expected Chinese characters in teh response body, please ensure you are including the following header with each request:
Content-Type | text/xml; charset=utf-8
Using this same header without the charset=utf-8 extension - IE, Content-Type | text/xml - may cause your request tool to incorrectly display these characters due to language configurations on your machine.
