In my case the browsers are able to display it, but I'm often unable to
decrypt it.

I've got no issue to read the examples in the German Wiki, I'm also able
to solve the arithmetic problem from the examples.

In real live they most of the times are completely unreadable for me.
Perhaps I'm a computer and I only guess that I'm human.
