Get font unicode value from a unicode font

I need a desktop program to get the 'Unicode values' that are defined in a Unicode font. Output is to be in Hexadecimal notation, such as '0000' '4E00' '5E3A' etc.. I actually got this program made a year ago. And I have full source codes (in MS Studio C++). Now I need to add an extra function to it. Yet the original coder's account is closed. So I post this bid for a new coder to make this additional function. What I want to add is 'For each Unicode value in the font, say 5B00' that is actually blank (no glyphs, totally blank) should be marked with a * in the output text file. Originally I paid 20 dollars for this program. For this additional feature I'll pay 10 dollars. But you need to be of good track record to be considered. ## Deliverables
