Title: Proposal for encoding the Khmer script in ISO 10646

Source: Michael Everson
Status: Expert Contribution
Action: For consideration by JTC1/SC2/WG2

This is a document the technical content of the forthcoming proposal to encode the Khmer script in ISO 10646. This proposal is a minor revision of a proposal by Hugh McGregor Ross, from ISO/IEC JTC1/SC2/WG2 N1321.

There are still some outstanding issues regarding the encoding of Khmer, and participation of Cambodian experts will be very welcome. Firstly, are the glyphs at 1436 and 1437 correct? Secondly, the mapping of the vowel signs to the independent vowels is still a bit uncertain. Lastly, the unification or non-unification of a vowel sign with another is still queried. An issues document has been prepared with more information on these questions.

Positions U+1400 -> U+147F are proposed for the Khmer block.
