Description
It would be nice if the Arduino-IDE would support fonts with special glyph-ligatures like the font "[Fira Code](https://github.com/tonsky/FiraCode)" like most other modern IDEs do.

Contributor guide
Research direction
Start by locating the Arduino IDE 1.x editor and font-rendering entry points, then check how a programming font such as Fira Code is currently loaded. Confirm the scope with a small rendering check; done means supported programming fonts display their glyph ligatures correctly without breaking ordinary editor text.
