• Advances in computers and computer networks
  • Due to the advent and the huge popularity of the World Wide Web, everyone want have his/her own website on the web.

  • When people from non-English speaking country try to set up their websites, they encountered a problem:

    The ASCII code standard can only represent the English Alphabet !!!

    Chinese characters, Hebrew letters, Arabic letters, etc, etc cannot be encoded in the webpage

  • So an international committee is setup to define a standard code for all characters used by all languages in the world.

    This universal character code is called the Unicode Wikipedia page: click here

  • Unicode:

    Unicode = a universal code to represent all symbols used in human communication The unicode uses 16 bits code words Therefore: We can represent 216 = 65536 different symbols in Unicode
