If you want to check a link before pasting or clicking, see if the final l in html is removed when you put the mouse pointer after it and you click backward, then replace it.

If it has this stuff, it does not show, but you will have to click twice before actually seeing the l disappear, then you just make an l normally, replacing the l, but not the invisible additions that sometimes show up as "%EF%BB%BF"/HGL
