Squares on custom typeface

Question

I am creating a TypeFace with this code:

setTypeface(Typeface.createFromAsset(context.getAssets(),"fonts/"+ fontName)); 

It is using ttf file to create this font.

When I try to use UTF-8 turkish strings to display it works on many devices, but in Samsung Galaxy S3 it creates unwanted squares on i chars.

Answer 1
