Remove "strange" characters when pasting into a field

This is probably a very low-priority and kind of controversion suggestion, but:

My workflow includes having to copy-paste from a PDF to a Pipefy field. As might be known, some PDFs are not optimized for copy-pasting, leading to the pasted string including certain characters, like the zero-width-space, that are just annoying to work with and in probably all cases unwanted.

I would consider it nice, if you could escape/highlight/remove such probably-unwanted characters after copy-pasting. That would make certain things in my pipeline easier afterwards.
