Wide char is similar to char data type, except that wide char take up

twice the space and can take on much larger values as a result. 

  char can take 256 values which corresponds to entries in the ASCII

  table. On the other hand, wide char can take on 65536 values which 

  corresponds to UNICODE values which is a recent international standard 

  which allows for the encoding of characters for virtually all languages 

  and commonly used symbols.
