Ambiguous unicode character decoration shows in settings.json but doesn't explain on hover #168470

  "terminal.integrated.wordSeparators": " ()[]{}',\"─‘’",

The decoration doesn't show up all the time 🤷

Are you sure it is the same text in both cases?

I get highlighing here:

"terminal.integrated.wordSeparators": " ()[]{}',\"-‘’",

But not here:

"terminal.integrated.wordSeparators": " ()[]{}',\"─‘’",

The reason is that the system does not now that ─ is confusable with an ASCII character (-). This is because the unicode confusable data is not very reliable (but we never claimed that this heuristic we use is safe - in untrusted workspaces both cases should be highlighted though, but there we highlight every non-ASCII character)
