Yes. On my computer. In my editor. That I am using…because I like ligatures, because they make my code easier to read. For me.
Use of ligatures on my setup does not force anyone else to use them? They’re not “viral” like a language feature.
“Oh but what if the >= Unicode symbol ends up in your source code and you don’t notice because you’re using ligatures?”
Is this the most contrived issue ever? Yeah and what if someone runs “find and replace” using Unicode confusables on my codebase? That’s arguably worse and requires no special font features. Plus I suspect most programming languages would throw an error immediately if you used the >= symbol instead of the pair.
If you don’t like ligatures, that’s fine, but there are those of us that do, and our font preference isn’t a threat to you.
