The Unicode Character Set
This unified character set is the result of
the work of the Unicode Consortium and the
International Organization for
Standardization (ISO). The former developed the Unicode Project and
the latter the ISO 10646 project but they merged onto one.
In
Unicode, each character maps to a Unicode code point. The rendered
version of the character is called glyph and one glyph or more
glyphs can be depicted to represent one character. Unicode is not a
16 or 32 bit code, each Unicode code point is an abstract entity and
there is no limit to the number of characters mapped. The current
Unicode standard version 4.0 defines less than 100,000 code points,
divided in 17 planes with 65,536 code points each. Plane 0 has
characters for most of the modern languages and it is called the BMP
(Basic Multilingual Plane).
