[Date] August 6, morning [What happened] 
A reader tells me there is a small notice in his copier's admin panel about character substitution. On his device, the “bug” can be avoided by setting compression from “normal” to higher. As a consequence, the issue must have been known by Xerox – so why was nobody telling us? As the notice only occurs when adjusting the setting in the admin panel, the implications, however, stay the same. People may create false figures without knowing. Anyway, I write a blog post presenting this workaround.
