Are you sure for Dari? They should be the same as those for farsi.
Dari and the Farsi keymaps (and keyboards) are different from eachother. The Dari keyboard has additional Pashto letters and the Iranian currency symbols is replaced by the Afghan currency symbol.
See [1] for a picture of the Dari keyboard layout . 1: http://www.evertype.com/standards/af/af-locales.pdf Regards M. Emal Alekozai
