Abstract
An apparatus and method for providing Unicode support in legacy operating systems are provided. With the apparatus and method, a focus hook module, keyboard hook module, and keystroke conversion module are registered with the legacy operating system. The focus hook module determines the currently active application and whether the currently active application is Unicode capable. The keyboard hook module receives keyboard events from an input interface and sends those keyboard events to the keystroke conversion module. The keystroke conversion module converts the keyboard events into Unicode characters which are sent back to the keyboard hook module. The keyboard hook module then stores the Unicode characters in a temporary storage memory, e.g., the clipboard. The keyboard hook module then sends a command to the application to paste the contents of the temporary storage memory to the currently active application.
