Copying a UTF-8 URL from browser's address bar, gives only the ugly encoded one

You can add 'space' at the end of URL in address bar, then you can select it all and copy it directly.

You can select URL without selecting scheme (e.g. http://), and copy it. This will give you what you expected.

P.S. The point is to select only part of the link. E.g. you can select whole URL without first character and than add it manually.

You can use Chrome Extensions like below:
