The Dzongkha keyboard layout scheme is designed as a simple means for inputting Dzongkha (རྫོང་ཁ) and classical Tibetan (ཆོས་སྐད) text on computers. This keyboard layout was standardized by the Dzongkha Development Commission (DDC) and the (DITT) of the Royal Government of Bhutan in 2000. It was updated in 2009 to accommodate additional characters added to the Unicode & ISO 10646 standards since the initial version. The Dzongkha (dz) keyboard layout is included in the XFree86 distribution.
