This and various other symbols can be typed into your email, word processor, etc..
The following chart will show you the symbols (Characters). To use the chart, find the symbol (the degree symbol is 167).

In the document, put the cursor where you with the symbol to be, then press and hold the ALT key down and type the number on the number keypad, then release the ALT key.
