Using Material Design Icons
To pick and icon scoll through the list of icons on the Material Design Icons Cheat Sheet. The icon font library is often updated so make sure you are using the correct cheatsheet for the version included. Newer versions will contain icons not available in older versions, and may also replace some icons. The cheatsheet is also included in our distribution, next to the .ttf file.

The string that is copied is just a hexidecimal index number but it must be made into a python compatible hexidecimal format by presceding the regular string with a '0x'. For example, if the hex code that was copied is 'F0EF4' the python hexidecimal notation is 0xF0EF4. Therefore, in TouchDesigner paste the hexidecimal string code into an expression of the format:
or more specifically in the case of 'F0EF4'
