How to read the table

ASCII is a 7-bit character set, so every standard value fits between 0 and 127. The binary column is padded to eight digits because computers commonly store text bytes in 8-bit units.

ASCII, Unicode, and UTF-8

ASCII covers English letters, digits, punctuation, and control characters. Unicode covers many more writing systems and symbols. UTF-8 keeps the ASCII values unchanged, then uses one or more bytes for additional characters.
