How to create Mac Command Option etc symbols in Illustrator CC windows

Hello,

I am making flat keycap icons for eLearning and need to find a way to create the symbols (rather than text) icons for keys such as mac command and option but in a Windows version of Illustrator CC. I have tried using unicodes but could not get a result; This is probably because all the unicode does is point to a glyph and I don't have the right font so I keep getting a different symbol inserted.

Could anyone tell me how to proceed? Am I right thinking I need to find a font (but which one?) that carries those symbols first? Is there another way?

Thank you for your suggestions.

Best;

Chris
