Degrees C Symbol on serial OLED's (UART)

How to get a degree symbol on the serial OLED's?

I always getting something like this: "°" instead of only the "°".

I think it has something to do with the UTF8 or Latin1 conversation.

 The module will not support UTF8, it only support ASCII table, the code of degree symbol in ASCII table is 0xB0
