The Chakma alphabet (Ajhā pāṭh), also called Ojhapath, Ojhopath, Aaojhapath, is an abugida used for the Chakma language and which is being adapted for the Tanchangya language. The forms of the letters are quite similar to those of the Burmese script.

The script is included in Unicode version 6.1.0.

Chakma is of the Brahmic type: the consonant letters contain an inherent vowel. Consonant clusters are written with conjunct characters, and a visible vowel killer shows the deletion of the inherent vowel when there is no conjunct.

Four independent vowels exist:  a,  i,  u, and  e. Other vowels in initial position are formed by adding the vowel sign to  a, as in  ī,  ū,  ai,  oi. Some modern writers are generalizing this spelling in  i,  u, and  e

One of the interesting features of Chakma writing is that CANDRABINDU (cānaphudā) can be used together with ANUSVARA (ekaphudā) and VISARGA (dviphudā):

Like other Brahmic scripts, Chakma makes use of the MAAYYAA (killer) to invoke conjoined consonants. In the past, practice was much more common than it is today. Like the Myanmar script, Chakma is encoded with two vowel-killing characters in order to conform to modern user expectations. As shown above, most letters have their vowels killed with the use of the explicit Maayyaa
