Definitions

AAT (Apple Advanced Typography) fonts

the TrueType fonts especially designed for use with ATSUI. Like OpenType

fonts these fonts have special features such as swashes, contextual forms,

ligatures etc. These fonts are widely presented among system fonts in Mac

OS X and are supported in Cocoa applications.

AFM (ASCII Font Metrics) file

A text file that contains the metrics information for a PC Type 1 font.

Alphabet/Script

the collection of characters used to write a particular language. “The”

alphabet (as North Americans and English know it) is the script for the

English language, Latin script is the script for most European, South-

American and some Asian languages. Cyrillic script is used in all Slavonic

languages (Russian, Ukrainian, Serbian, Bulgarian and many others). Note

that a script usually includes many more characters than necessary for the

one language. Latin script, for example, includes more than 200 characters.

ATSUI (Apple Type Services for Unicode Imaging)

Apple's technology and a set of routines that enable the rendering of

Unicode-encoded text with advanced typographic features. It automatically

handles many of the complexities inherent in text layout, including the

correct rendering of text in bidirectional and vertical script systems.

Character

a symbol used in writing. The letter “A”, for instance. Every character has a

name, which is used to identify it.

CMap (character map)

A table relating an encoding to a set of internal computer codes. For

instance the computer may use the numbers between 1100 and 1356 to

represent the characters in a font. When it needs character number 1234 it

looks at the CMap table to find the corresponding code, which, in turn,

directs it to the appropriate glyph.
