// Fow now Rio implement programming ligatures based
// on pre-compiled combinations and not on font features
//
// Some good resources about ligatures in programming fonts
// - https://practicaltypography.com/ligatures-in-programming-fonts-hell-no.html
//
//
// Good to remember that programming ligatures they contradict unicode
// so it should only work in the renderer level, any time an user copy
// the sugarloaf content it should come as the original sequence of characters
