I've added them to a code snippet because SMF converts them to links. If you hover over the links you'll see one URL looks a lot different to the other. Most browsers let you know that the URL has a non Latin character in it.
If you copy any past the url from the code snippet the browser will not change the URL until you visit the site

I always check the url before clicking. It's saved me a few times.
