It's not Scribus, but I think here is this problem best discussed
I wrote my first book 1992 with Calamus on Atari TT.
About 2005, somebody was so nice to convert my old Calamus files from 1992 to
a PDF.
I used SWISS 100, but this font seems to be broken, the conversion to the PDF rendered SWISS100 not like expected.
At starting to write my second book October 2011, I changed from Calamus to Scribus.
I discovered Swiss_721_Black_BT.ttf should be most similar to the old Swiss100
Is it possible to exchange a font in an existing PDF?
Here is the PDF

hi founder
theoretically it should work in acrobat pro. with the 'touch up tool' you can select the text. in the context menu under 'properties' → 'text' you can select a new font – but i haven't any experience with this...
