System for dynamic strings & inline icons [Unity]

Input glyphs. Action icons. Keybind icons. They have many names, but they all refer to the helpful icons you see in games that tell you what buttons to push to do a certain action. They can be as simple as hard-coded bits of text, or as complex as dynamic strings that adjust based on keybinding and the active controller. This article focuses on achieving the latter. Specifically, ones inline with tutorial text.
