Unicode Map - database of Unicode characters
Unicode serves as a standard for computers to display character data from any language.
There are many variations of the Unicode standard, including UTF-7, UTF-8, UTF-16, UCS-2, as well as Big Endian / Little Endian byte order variations.
Traditionally, the ASCII standard used 1 byte to store 1 character, resulting in 256 combinations.
Unlike the ASCII standard, Unicode character data utilizes multiple bytes per character.
This increases the number of possible characters, and this may vary depending on what variation of the Unicode standard is in use.
