[Help] Extracting Post Links

I have used this method here found in the forum to see my wp urls,


and ,i dont know why some of the links comeback as:

mywebsite /computer-r%d0%b5%d1%80%d0%b0%d1%96r-t%d1%96%d1%80%d1%95

Why is not the full name of the post instead? ,if i do paste the link in browser and click enter , it goes to that page with a normal name ,but why does: %%,numbers,etc in the url link?

Thanks for any advice.
