Quran App Fonts issue

Hey guys,

I am making a quran application in which i am using fonts from Tanzil.net and noor-e-hidaya't font. i am using madni and urdu mushaf. But i just ran in to a problem of zer, zabar, pesh and tashdeed in fonts of quranic text. In both of the fonts i am using , they have problems of some particular symbols either of zer, zabar, pesh and tashdeed.
Can anyone please suggest me some of the fonts lists that can work great and efficiently without any issue because everybody knows that these punctuations are so delicate that missing anyone of them can change the meaning of aya'h dramatically. I would appreciate if anybody could help me out in this. Thanks in advance.
