3Character Sets – Unicode - Reading
R 47
The older character sets of ASCII and extended ASCII use 7 and 8 bits. Unicode is another character
set that maps binary combinations to characters.
The problem with ASCII is that it has a maximum of 128 characters that it can store. Japanese people
need to know over 2000 characters and the Chinese alphabet contains around 50 000 characters.
Therefore the character sets need to have more bits to store them. Unicode is an international
system of storing these characters.
Unicode currently stores over 100 000 characters. There is a 16 bit (2 byte) version of Unicode which
16
32
contains 65536 (2
) characters. A 32 bit (4 byte) version can store over 4 billion (2
) characters, far
more than required for every language in the world.
Unicode uses the same codes as ASCII from 0~127.
The following table shows a sample of characters available in Unicode. The black lines in the table
show sections of the character set which have been left out.
