Pure Programmer
Project: Character Types
We can group characters in the Unicode character set by attributes that the characters have. Is it a letter? Is it a whitespace character? Is it a control character? Write a program that defines a string of interesting characters. Then iterate on that string, character by character, printing out the character and its attributes using the character typing functions.
