i think they are complaining 2 points at a time..
i.e.

1. The Scheherazade Font dont look the same on N900, as it should be.. i.e. as seen on PC.

2. The font they are looking in Holy Quran App is not looking like Mushaf font..(aka KFGQPC) or the font used in Quran (Book)..

I think the new font which you will be implementing will solve this issue.. (this problem is not that critical at the moment, because it gets solved when you put the new font i.e. Amiri font ).
