Tibetan

[scossu]

I have received feedback from Tibetan catalogers about some discrepancies between Aksharamukha and the ALA-LC Tibetan romanization table using Roman (IAST) as the target script.

Is the intent of Aksharamukha to conform to ALA-LC standards?

The list of discrepancies is the following (ALA-LC to the left, Aksharamukha to the right):

Vowels:
ཨེ          e                   e ( ĕ, æ, ǣ, Others)
ཨོ          o                   o (ŏ, Others)
ཨཱ          ā                   ā , (ô, others)

Consonants:
ང           nga                 ṅa  

Missing Tibetan script in Aksharamukha:
ཅ  ཆ  ཇ ca cha ja                   Missing
ཉ       nya                     ña
ཙ       tsa                     ca
ཚ       tsha                    cha
ཛ       dza                     ja
ཝ       wa                      va

Fixed. Aksharamukha now supports Tibetan LoC. It is already live.

I will update the python package in a couple of days.

Wonderful. And thanks for the link to the ALA-LC supported languages. I will test when the Python module is updated and let you know.

I have already updated the package.

The test cases for Tibetan are here:

https://github.com/virtualvinodh/aksharamukha-python/blob/main/aksharamukha/test/loc_indic_test_cases.py

I only test for cases that deviate from ISO 15919. But it should capture all LoC-specific rules.

I'm closing this issue now. Feel free to open a new issue if you find anything.
