Sigh - the error manifest itself in the rubrics

Sorry but I do not understand.

There is a to me unknown bug deep in Rubrics. It is seemingly related to lines with only an image. Images are stored in Text in a special character (character 1). If that character appears in alone a line (between two CR), it will fail in some - but not all cases.

I tried to patch the problem by enclosing the image in two zero-width non-printing spaces (unicode is full of weird things). This worked fine until it turned out that some fonts do not know that character, and put two ugly boxes instead.

PR #588 just ad a blank on each side, and the problem goes away again - at least for now.

Further, the issue might be related to some changes I had to make a year ago to get it to redraw embedded images in the first place.

I could surely need some help by a rubrics expert, but it is my understanding that there is no such expert around, which is why I made this patch.

I included the PR with the patch, but does not close this issue!
