I need to know how I can convert symbols/icons to font glyphs in sketch app? Does anyone know how to do it? Thank you in advance
Just right-click the symbol at the place it's being used and choose "Detach from Symbol".
EDIT: Misunderstood the original question. If an icon font is what you want, here's a tutorial for that: https://medium.com/sketch-app-sources/font-icons-workflow-with-sketch-and-grunt-16b161d97c5e#.vwumravuc
