looking for font(s) having opposite style but symmetrical H and N characters. I wish to write the name HassaN which looks the same from both side and completely symmetrical.
What you're looking for is called an ambigram typeface. They're hard to find and most likely aren't free to use if you do find one. I would take a look at these generator and use them as a basis to create your own typeface for your name. http://www.dezineguide.com/inspiration/25-best-ambigram-generators-and-examples/
