A method providing for input of any script/language, on any computing device, mobile or otherwise by conveying Unicode characters to the computing device instead of keyboard scan codes that require further processing. The method includes all script/language processing independent from the computing device, permits changing input script/language “on-the-fly”, provides for a universal platform-independent method to select each particular script/language, and requires no language-specific support on the computing device, other than the ability to display the selected script. The method also provides for input of commands and backward-compatible input using legacy keyboard key codes.
