Core Foundation Text & Fonts Technical Notes

Text manipulation consists of creating, managing, storing, and searching for text strings. Mac OS X programming interfaces provide capabilities that range from basic text input and display to sophisticated text encoding conversions, text-search capabilities, and document summarizations. To control how text is laid out and rendered in the written representation of languages, Mac OS X programming interfaces also enable sophisticated typography. For example, applications can precisely position individual glyphs and lines of text, draw Unicode text at any angle of rotation, kern text, and activate and deactivate fonts.
