@Samir-Sumantlal-Shah said in Hopefully Notepad++ can display correctly ...:
GujaratiMT
Searching suggests that “Gujarati MT” is a Apple system font that is not available elsewhere.
Are you by any chance using the new MacOS port of Notepad++? That port is not maintained or endorsed by the creator of Notepad++. You would have to raise issues with it in its own repository. We’re not going have a clue here.
