To write Khmer with a computer also for Khmer people is not easy, but many Khmer are not able to read English. The Khmer Alphabet has about 72 Characters and same sounds of Khmer simple don't exist in English.

There are many Cambodia maps with English writing available. For Children in School, there is no map in Khmer. There are many Children in _Cambodia that are not able to read, even if they go to school. A reason for that is, that they simply have nothing to read.

Maps with location names

Wikimedia Commons has a large map of Cambodia in two forms: one with legend and placenames in English and another in Khmer. Apart from the text, the maps are identical.


(follows spelling from Bureau of Geographic Names)


(same map with Khmer placenames)

There are multiple transliterations of Khmer placenames into English. One thing that's needed is a table showing Khmer names with the corresponding English names used. -- Rsperberg 04:47, 30 July 2011 (BST)
