Chapter 6 - Script Manager
This chapter describes the Script Manager, a core component of the Macintosh script management system. The Script Manager oversees script systems and gives you access to their features.Read this chapter if you are writing a multiscript text-handling application and need access to the general settings and script-specific information provided by the Script Manager. Read this chapter also if you are writing a specialized application that parses source code or converts text among subscripts. Read this chapter also if you wish to modify the features or functions of an individual script system.
Before reading this chapter, you should be familiar with the Macintosh script management system, as described in the chapter "Introduction to Text on the Macintosh" in this book. Useful related information is found in the appendixes "International Resources," "Keyboard Resources," and "Built-in Script Support."
This chapter--and this book--do not catalog the features of individual script systems. More detailed information on the world's writing systems and the Macintosh script systems developed to support them can be found in Guide to Macintosh Software Localization.
The chapter gives a brief introduction to the Script Manager, and then shows how you can use the Script Manager to
- control default settings for text handling
- obtain information about a script system
- convert text through tokenization or transliteration
- modify a script system by replacing its resources or--in some cases--its routines
