A simple shape specification byte contains vector length and direction encoded into one specification byte.
Special codes can be used to create additional geometric forms and specify certain actions.
Text fonts must include a special shape number 0 that conveys information about the font itself.
This topic contains sample files that help extend the font characters provided with AutoCAD.
Some languages, such as Japanese, use text fonts with thousands of non-ASCII characters. In order for drawings to contain such text, AutoCAD supports a special form of shape definition file called a Big Font file.
A single Unicode font, due to its large character set, is capable of supporting all languages and platforms. Unicode shape definition files are virtually identical in format and syntax to regular AutoCAD shape definition files.
You can modify shape definition files to improve their ability to display superscripts and subscripts.
