Answer / vipul

ANSI: This standard provided 256 different symbols that a
computer can use. It was quick, efficient, and easy to
implement. All modern operating systems fully understand
ASCII.

UNICODE: Unicode which allowed for up to 65,536 different
characters. Since Unicode is more complex it is not
implemented on many operating systems. In terms of
Microsoft; Windows NT, Windows 2000, Windows XP, and
Windows 2003 support Unicode as will all future releases of
Windows.
