  Re: Unicode
  
  Actually unicode provide you 16-bit addressing format.So you can able to address power(2,16) bits of information.
  While in ASCII it's 7-bit(unsigned) and 8-bit(signed).I think you know that ASCII provide you addressing for all the keys what you have on your keyboard.
  With the help of UNICODE you can able to write all the language like hindi,english,japanese etc.
  
  Java provide UNICODE features and with this it can also support ASCII.You must hear about some converters in java like InputStreamReader(which converts bytes to characters),parseInt....etc.
  Due to this UNICODE feature in Java you can able to write many types of languages on applets.

  Hi Mohit there is a correction, Unicode is not used to address, it was developed to make a character format universal. The previous character format used was ASCII which had 0-127 characters.
  Due to limitation of characters in ASCII it was decided to extend its capability to 8 bit, which never came true, so Unicode Consortium created a universal coding system to provide enlargeable character set which is known as Unicode now. Sun adopted Unicode character format to build Java to provide wide usability of their programming language, without any modification, when regional language problem will occur.
  
  Originally Unicode was a 2 byte code set, but as per today it is 4 byte code i.e characters that available in Unicode to use are 2^32(4,29,49,67,296). And i think this value is quite able to accommodate characters of all languages across the world because Unicode already supports all kinds of characters and more than half are still empty characters that will be filled if we ever felt to add any extra language characters.

  Ya you are right!!
  Actually i want to say that 16-bit addressing will be done in order to provide UTF-16.

  What do you mean to say??
  .
  Up to what i know in order to use signed data types you must need 8-bit character encoding and that comes with ISO(it will provide you unsigned ASCII).
  7-bit character encoding(ASCII) provide you only 0 to 127 not -127 to +127.

  Sorry that was a writing mistake, i meant ASCII committee decided to extend ASCII characters by increasing number of bits more than 8. This was planned but the feature never came to existence.
