Unity WWW Text response is garbled - web

Question

I am using the sample code from the Unity website for the WWW class to make an API request but the text response is garbage. It looks like ����. When I log the response headers, I get a 200 response and everything seems ok except that the CONTENT-TYPE is image/jpeg. I have tried several different random .json files to test it out and they all return the same thing. Requesting an image to use as a texture does work.
public class SpeechReq : MonoBehaviour {
//public string url = "https://gist.githubusercontent.com/wethecode/1f79baf168680afb0f2d/raw/755f9fb71dcc34df811b4bc26448d88a0f97f34d/snippets.json";
public string url = "https://gist.githubusercontent.com/damienh/fea91ab710475d499a09/raw/893065428badd8bfdc7b39fe17675b8aa031ac51/gistfile1.json";
IEnumerator Start()
{
WWW www = new WWW(url);
yield return www;
string respText = www.text;
Debug.Log(respText);
//Output: ����
byte[] resp = www.bytes;
var str = System.Text.Encoding.Default.GetString(resp);
Debug.Log(str);
//Output: ÿØÿà
if (www.responseHeaders.Count > 0)
{
foreach (KeyValuePair<string, string> entry in www.responseHeaders)
{
Debug.Log(entry.Value + "=" + entry.Key);
//Output: HTTP/1.0 200 OK=STATUS
//...
//image/jpeg=CONTENT-TYPE
}
}
}
}

The WWW class's .text method returns the UTF8 Byte Order Mark at the beginning of the response by default. See a description of the BOM here
You could try:
string jsonText = "";
if (string.IsNullOrEmpty(www.error))
{
jsonText = System.Text.Encoding.UTF8.GetString(www.bytes, 3, www.bytes.Length - 3); // Skip the UTF8 BOM
JSONObject myObject = new JSONObject(jsonText);
}
