[2] The earliest Mon inscriptions, all undated, have been paleographically dated to the 6th century CE; they are found in Nakhon Pathom and Saraburi (in Thailand).
[5] A number of Mon stone inscriptions have been found in Thaton and its environs, Lower Burma.
Its writing style is very similar to the Dinaya inscription of 760 CE, written in Sanskrit, with the Kawi script of Old Java.
[citation needed] During this period the Mon writing characters can similarly be divided into two or three types, but the language was not much different.
[7] The script has undergone considerable modification to suit the evolving phonology of the Burmese language, but additional letters and diacritics have been added to adapt it to other languages; the Shan and Karen alphabets, for example, require additional tone markers.
[8] There is a great deal of discrepancy between the written and spoken forms of Mon, with a single pronunciation capable of having several spellings.
Whereas in Burmese spellings with the same diacritics are rhyming, in Mon this depends on the consonant's inherent register.
The Mon script has been encoded as a part of the Myanmar block with the release version of Unicode 3.0.
