), it lacks full-coverage for Indic scripts of other languages. Specifically, the support for Dravidian short-vowels 'e' and 'o' is considered ambiguous (since Indo-Aryan phonology does not differentiate them from long-vowels 'E' and 'O'). Also, the schwa used in languages like Bengali ( � and Assamese ( � differs from that of other languages ( �, causing a dissonant feeling when typing those languages. Moreover, although both Bengali and Assamese use Eastern Nagari, the phonology of Assamese varies from that of Bengali to a significant extent, causing more friction while typing Assamese.
The support for many phones of other languages like Dravidian, Hindustani nuqtas, Sinhala etc. is considered patchy and not consistent across implementations due to lack of standardization. Also, almost no ITRANS implementation fully supports languages like Kashmiri, Sindhi, etc.
New version
The ambiguity around Dravidian short-vowels 'e' and 'o' support has been addressed with a new ISO15919 compliant coding scheme, which is uniform across all supported languages/scripts, including nukta. The old version ITRANS 5.3 is maintained for backward compatibility.
The changed ones are listed below:
The newly launched revamped package supports both the old ITRANS V-5.3 scheme as well as the ISO15919 scheme.
In addition, the new package can be customized for any specific INPUT codes.
