ADE Font Bug
another bug that I have just recognized with 1.7.2 is related to font embedding.
Aparently it seemed to work for some fonts of my sample epub file but not all.
Later on I realised the issue seems related to the file size of the fonts.
One of my fonts was 112kB whereas the others just around 60 kB.
Once I made it smaller, it embedded fine.
And good news the 1.8 Preview version doesnt display this problem.
