I know how to present number as a bitmap, for instance:
17 = 010001
11 = 001011
This is about numbers, but what about letters? Is there a way to do this? For example:
w = ??
[ = ??

Everything on your computer is represented as a sequence a bits, what you are calling a “bitmap”. So the answer to your question is yes, characters have a binary representation, along with integers, floating-point numbers, machine instructions etc.
Different languages use different binary encodings for characters, Objective-C uses Unicode. See the section Understanding Characters in the NSString
documentation.

You might as well jump in at the deep end and visit www.unicode.org.
Letters are complicated. And anyway, representing them as a bitmap is a bit pointless, isn't it?
