it's no big deal

The corruption comes from cutting and pasting from one website to another site that has not defined a certain symbol, so it comes out gibberish. The https warning is a common warning that comes before clicking on sites that have not paid their https fee. The https fee is like a license plate that goes on the back of an automobile. Most people buy theirs from the DMV, but BC just draws their own license in Microsoft Paint and prints that onto the license plate area. Of course no one is fooled. We can all now see that this jalopy is unlicensed. Your internet browser is just warning you to watch out, since many unlicensed sites have bad ideas and naughty downloads that could mess up your computer. Many, but not all, since just being self documented isn't necessarily a crime... yet.
