Unicode is a system which ensures that characters appear the same across any program or platform. Computers only use binary code to store and send data, which means that all characters are actually made through a series of 1s and 0s. Unicode is a practical agreement to use the same 1s and 0s to represent each letter, symbol, or emoji. k = 00000000000000000000000001101011 W = 00000000000000000000000001010111  = 11110000100111111001000110001100 Unicode is a dictionary of all these numbers and to which characters they correspond. There are currently over 137,000 characters which can be used to create distinctive fonts.
