Imagine having to transfer 4 times as much data as ASCII text!įortunately, character encoding can make it more efficient to store and transmit Unicode text. In the Internet world, this is a huge problem. Problem? While Unicode provides enough space for all the characters used in all languages, storing and transmitting Unicode text is not as efficient as storing and transmitting ASCII or Latin-1 characters. Currently at version 8, Unicode is used in Java, XML, ECMAScript, LDAP, etc. A unique number in Unicode represents exactly one character.

This body attempts to include all characters in all languages in the world into one single character set. Unicode is a character set developed by a non-profit organization called the Unicode Consortium (. To unify all these characters sets, a computing standard called Unicode was created. In total, there are hundreds of different character sets for all the world languages. The Japanese use a different character set for their language too. There are thousands of these characters and eight bits are not enough to represent all the characters in the character set. For example, each character in the Chinese language represents a word, not a letter. Chinese and Japanese are examples of languages that use different character sets. However, not every language uses Latin letters. As such, storing and transmitting text written in an 8-bit character set is most efficient. An eight-bit-per-character character set is convenient because a byte is also 8 bits long. This character set contains all the characters required for writing text in many of the western European languages, such as German, Danish, Dutch, French, Italian, Spanish, Portuguese and, of course, English. Each character in ISO-8859-1 is represented by eight bits as well. This character set is called extended ASCII and each character is represented by 8 bits.ĪSCII and the extended ASCII are only two of the many character sets available.Īnother popular one is the character set standardized by the ISO (International Standards Organization), ISO-8859-1, which is also known as Latin-1.

The ASCII character set was later extended to include another 128 characters, such as the German characters ä, ö, ü and the British currency symbol £. These include the lower case and upper case Latin letters, numbers, and punctuation marks. There are therefore 128 characters in this character set. Each character in the ASCII is represented by 7 bits. Traditionally, computers in English speaking countries only used the ASCII (American Standard Code for Information Interchange ) character set to represent alphanumeric characters.
