The Unicode specification includes a huge number of different letters,
symbols, characters, mathematical and musical symbols, dingbats, etc (known
collectively as 'glyphs'). Each glyph is given a unique number and any
piece of software that supports Unicode can, in theory, display any of
the glyphs. In practice, this only happens if you have Unicode enabled
fonts containing the relevant glyphs.
Unicode enabled fonts generally include only a subset of the total Unicode
specification, for example Latin, Greek, Cyrillic and Thai, though there
are a few fonts, such as Arial Unicode MS, which include a large proportion
of the specification. Arial Unicode MS is included with Microsoft Office 2000.
The latest version of Unicode (6.0) specifies nearly 110,000 glyphs. The following
scripts are supported:
