Primarily, I wanted to make a simple notepad editor, not a hex editor. Binary editing is a feature, but not the main purpose. Many other text editors use escape characters to mimic the way that hex editors edit text, and while this is a very rational solution, I wanted a simple but elegant solution that would allow full control while not adding in a lot of overhead, and I came up with this one. Every character is still distinguishable for the most part, but the main purpose was always to display it as legible text rather than hexadecimal.
