Adding Symbols in Text Box

I am working with our group to start creating details in Revit. We came across the issue of adding symbols in our text. We started by just typing abbreviations, this added to our normal note size. I did some research and found Revit supports Windows Character Mapping.
Here are the simple steps to do this;
1. Ensure Number Lock is on
2. Hold the [ALT] Key
3. While Holding [ALT] type in code suing Number Key Pad (Number pad on right side of keyboard
4. Release [ALT] Key
If I would like to add the degree symbol in a note all I have to do is Hold the ALT key and type in character map code "0176".

*You must use the number pad, traditional numbers above the letters will not work.

Some of the Standard Codes:
0176 Degree
0248 Diameter
0178 Squared
0179 Cubed
0177 Plus-Minus
0174 Registered
0169 Copy Right

**Laptop users can not use the numbers on the traditional keyboard above the letters. Majority of laptops have a number pad overlaid into the keyboard area that you can utilize with the number lock key and the same method.
***You can also utilize this same method in AutoCAD and other Windows Programs.
