Fonts in Pressbooks mPDF + Pressbooks

Now we have two folders with fonts. The one of Pressbooks and another in Pressbooks mPDF.

90mb in Pressbooks mPDF
40mb in Pressbooks

As the fonts are not the same. Is necesary to have that duplicity? is not possible to load the fonts in Pressbooks mPDF from Pressbooks in order to have the same syle in web and in pdf? or just to have the same fonts in both folders for a better compatibility?

Are the fonts on Pressbooks selected for a specifical reason? a deep review of the fonts is necesary?


This really belongs on
