enable / disable highlight-bad-chars for file type ?

I like this plugin. I hope to the highlight-bad-chars only works for the selected file type, such as ".c". 'Spell-Check' has the Grammars config option which is a list of scopes for which the package will check for spelling errors. It will be greater if such similar option is added for this package.

Sounds reasonable. PRs are welcome!

I have this need/demand as well. When I write LaTeX, a solo invalid char disables all the document, that's why I found this extension. But for other file types, those "invalid chars" is not invalid anymore. A workaround I am now using is the workspace configuration in VSCode.
