The degree symbol is the last character in the System5x7 font it is character 128 decimal or 200 octal.
This code:
oled.setFont(System5x7);
auto tempC = 25.0;
auto tempF = tempC*9/5 + 32;
oled.print(tempC, 1); // Use one decimal digit
oled.print(" \200C is "); // \200 is octal escape for degree symbol
oled.print(tempF, 1);
oled.println(" \200F\n");
Should print:
25.0 °C is 77.0 °F

That did work. Thank you Bill.
I can see it's been documented since 2018 here : https://github.com/greiman/SSD1306Ascii/blob/master/src/fonts/System5x7.h#L144
It did not came up in the search results within the repo when I looked for "degrees". Sorry about that.
Have a great day.

If you need symbols in cp437 you can use cp437font8x8 or Adafruit5x7. For Adafruit5x7 you must change this symbol in Adafruit5x7.h.
#define ADAFRUIT_ASCII96 0 // was one
To select the fonts use:
oled.setFont(cp437font8x8);
or
oled.setFont(Adafruit5x7);
The down side is that println() will no longer work since \n and \r are now this bullet, ◙, and eighth note, ♪.
You must use cursor positioning and clear line instead of println().
Also you must use escaped character codes.
