Receiving a strange response string from REST API

Hi,

I have been struggling with an issue for the last couple of days and I have not been to find a solution.

I am calling a specific REST API from my C# project and as a return I am getting a strange looking string.
I know that this string is suppose to be an Image but I am not been able to convert it:

The string (First Part) looks as follows:
"����\0\u0010JFIF\0\u0001\u0001\u0001\0�\0�\0\0��\0ZExif\ ........."

or
"�PNG\r\n\u001a\n\0\0\0\rIHDR\0\0\u0001\0........."

I know this is a JPEG File and the second a PNG but it doesn't matter what I do I am not able to convert it.

Note: I do not have access to the code of the REST API Server so I am only able to get the string response.

Does anybody know what format this is and how to get this back into a bitmap format?

What I have tried:

var result = coreApi.CoreGetGalleryImageV1("string", 188, 188);

byte[] array = Encoding.UTF8.GetBytes(result);
var ms = new MemoryStream(array);

Image x = Image.FromStream(ms);
