Profile picture for user arilio666

A Unicode system in the java programming language is a way to represent and support almost all of the well-known languages in the world.

  • It is comprised of a 16-bit character encoding standard.
  • So to support multinational application code this Unicode is represented to it.
  • Some of the characters use single-byte and some of the other characters use two.
  • To avoid these and overcome Unicode system was introduced where characters are represented with 2 bytes.

Some of the other standards before Unicode:

  • KOI - 8 (Russian)
  • ASCII - American Standard Code for Information Interchange (United States)
  • ISO 8859-1 (Western Europe)
  • GB18030 & BIG-5 (Chinese etc)
