This generates all the characters available in the character-set used in Coda. Many of the character codes do not produce printable/displayable characters. And some use different directions (right-to-left and top-down).
It is fascinating to see so many of the planets languages and writing systems (including braile & morse-code) represented here.
And its great to find some useful characters in there (icons, emoticons, special symbols, mathematical notations etc).
enjoy!
