> Sending “ffi” alone is an arbitrary decision. The font might have kerning between “ffi” and what comes before and after it, but you won’t get it. The font might not hav a ligature for “ffi” at all, but using kerning instead, so you will get kerning between “ffi” glyphs and not other glyphs which is arbitrary. It might be a cursive font that changes glyph shapes based on surrounding glyphs, and you will get that for “ffi” and not elsewhere which is arbitrary.
