I have managed to create a few ligatures in some font editing software such as birdfont. However after I have installed my font into windows and I load PhpStorm, I select my font with the ligatures I have created but PhpStorm can't seem to display them.
My question is, can I make ligatures for letter sequences like f u n c t i o n
or c l a s s
for example? These are non standard ligatures that don't come included with FiraCode but I would really like to be able to make ligatures for these sequences, I have made them externally but how do I get PhpStorm or any JetBrains software to recognize them?
