But notice is not an opinion that most fonts you see everywhere are not using ligatures. They are a subset which is the opposite of being universally adopted as norm. Which is the point I'm raising: The norm expects you to unambiguously interpret certain symbols and ligatures dilutes that normal convenience to read symbols unambiguously. Your brain acquired a taste to adjust the parsing of these symbols, that taste isn't universal nor is it the norm.
