How to print the Celsius degree sign?

Most fonts only support ASCII and don't have the degree symbol. I think the Adafruit5x7.h font may have it if you set ADAFRUIT_ASCII96 to zero.

Also the last character in System5x7.h is the degree symbol.

Other users have created fonts with special symbols using openGLCDFontCreator.

the last character in System5x7.h is the degree symbol.

How to use it? These code didn't work: oled.setFont(System5x7); oled.println("\127C");
