In PAF you can press the F7 key when you are any field that can accept input. It brings up PAF's character map.
But PAF Companion is limited to the English character set, so even if the characters dispaly in PAF they will not display in PAF Companion. (I believe that is true of all of the printing "Companion" software from Progeny Software, not just the PAF version. Maybe someone else in the list will know for sure.)
It might be necessary to shop around for different software to print the German characters, or try doing a descendancy report from PAF. I may find something for free.
