The URL contains escaped bytes unsupported by the UTF-8 encoding.

This is my first post to the forums, just wanted to let you know of the error message on 

https://www.instructables.com/id/Knockdown-Illuminated-SIgnboard-D%CB%8B%85g%0F%0B%7F/

I love the site, and can't wait to learn more!

Picture of The URL contains escaped bytes unsupported by the UTF-8 encoding.

I bet the bytes escaped from jail and now are wrecking havoc across instructables

Its possible that the author deleted the page, I looked at his home page and there are no instructables there. you could PM him and ask

https://www.instructables.com/member/NaritaTatsuya?show=INSTRUCTABLES

Oddly, his profile says that he has written two instructables, but that he has written no instructables - I'm thinking you're right about the deletion.
