How to get delta symbol in font

Can I show a capital delta symbol (triangle) using the built in fonts? I tried typing ALT+916 and ALT+30, which are codes I found online, but they did not work. I made a delta symbol in ms word using ALT+916 and tried to copy and paste it into squareline, but it did not work.

Any help is appreciated.

The is no delta symbol in the built in fonts. You need to generate new font with SquareLine, and add it as symbol.
