The 'Lucida Sans Unicode' also has it.

I know how to insert a special character in text, but not in a formula.

There is a function to change the font, in the attributes functions, but I can't figure out how it works (ie: I can't get it to show the U+2220 character).

...

Nevermind, I just got it. I found the page I needed in the help files to figure it out.

Basically, if anyone wants to know, I changed the 'Sans' custom font (Format>Fonts) from 'Arial' to 'Lucida Sans Unicode'. Then, with the special character in my clipboard, I pasted it as the second term of the fonts attribute function.

- Code: Select all Expand viewCollapse view
`font Sans ∠`

The angle special character (U+2220) showing up as a square.

In describing the current, this is how it would look like in Math (the angle character showing as a square):

- Code: Select all Expand viewCollapse view
`vec I = 10 font Sans ∠ -20 Amps`

Thanks to all who helped! And acknak, I love that Gary Larson's comic strip.
