Convert Unicode Characters to PNG or JPG

I have urdu unicode data like in text files. Following is just a sample from that

urduData='انداز میں صحافیوں کو بتایا کہ ہماری ملاقات اچھی رہی '

Now what I want to do is that I need to read each unicode ligature(there are more than 16000 valid urdu ligatures here I could also split them based on spaces for understandability) and display them in a 30x30 to 100 x 100 images with step size of 10 like 30x30,40x40,50x50....100x100. I would also be requiring to increase the font size based on the box for readability. How would I do that in MATLAB?
