Abstract

Devices and methods for providing Unicode support in traditional operating systems are provided. Regarding the apparatus and method, a focus hook module, a keyboard hook module, and a keystroke translation 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 the input interface and sends these keyboard events to the keystroke translation module. The keystroke conversion module converts keyboard events into Unicode characters that are sent back to the keyboard hook module. The keyboard hook module then stores the Unicode characters in temporary storage memory, such as the clipboard. The keyboard hook module then issues commands to the application to paste the contents of temporary storage into the currently active application.

Description

technical field [0001] The present invention relates to an apparatus and method for enabling Unicode input in a conventional operating system. More particularly, the invention relates to the ability to receive text messages expressed by converting keystrokes to Unicode even if the application is executing on an operating system that does not have Unicode support or for a particular selection of scripts. The input method editor's mechanism for converting keystrokes to the Unicode representation that can be used by applications that support Unicode. Background technique [0002] Contemporary operating systems such as Microsoft Windows 2000 TM and WindowsXP TM , to enable full Unicode input via the Input Method Editor (IME). Unicode is a superset of the ASCII character set, using two bytes per character instead of one. Therefore, the Unicode character set can handle 65536 character combinations instead of ASCII's 256. This allows many world languages ​​to be represented in...
