I prefer reading the ISPConfig manual on my tablet computer. It is Android, and I like to use FBReader. It is the best of PDF readers I tried, except looks like it has wrong info on font measurements. Some fonts display with wrong kerning. See attached screenshot, for example the first line in "Website quota" paragraph. Some characters are touching each other and some have too much space between characters. Other PDF-documents I read with FBReader do not have this problem. On the other hand, other PDF readers render ISPConfig manual OK, so I'm not sure where the fault lies. Could this trouble be looked into when next version of the Manual is published?
