The Difference Between Unicode and UTF-8 Unicode is a character set . UTF-8 is encoding . Unicode is a list of characters with unique decimal numbers (code points). A = 65, B = 66, C = 67, .... This list of decimal numbers represent the string "hello": 104 101 108 108 111 Encoding is how these numbers are translated into binary numbers to be stored in a computer: UTF-8 encoding will store"hello" like this (binary): 01101000 01100101 01101100 01101100 01101111 Encoding translates numbers into binary. Character sets translates characters to numbers.

Common values: UTF-8 - Character encoding for Unicode UTF-8 means Unicode Transformation Format (UTF). (U from Universal Character Set + Transformation Format—8-bit) is a character encoding capable of encoding all possible characters (called code points) in Unicode. The encoding is variable-length and uses 8-bit code units. The Unicode Consortium cooperates with the leading standards development organizations, like ISO, W3C, and ECMA. Because the character sets in ISO-8859 was limited in size, and not compatible in multilingual environments, the Unicode Consortium developed the Unicode Standard. The Unicode Standard covers (almost) all the characters, punctua...
