I now have a habit of copying and pasting things I receive in emails or generate with certain tools into a ascii-only notepad before recopying and pasting out, anything that I am posting or sending to others. Because I've thought about how easy certain services could track origin of content across platforms with non printing unicode or using unicode for homograph attacks. Makes me want a systemwide right click > "Paste and strip all but ASCII" command.
