A collection of scala and java classes for some basic character level processing for the Sanskrit and other Indic (kannada, telugu, etc..) languages, contributed by the open source sanskrit-coders projects and friends.
Some notable facilities:
* Transliterate text from one script or encoding scheme to another.
* Some grammar simulation.
Examples: see https://github.com/sanskrit-coders/indic-transliteration
Contributions and suggestions are invited at https://github.com/sanskrit-coders/indic-transliteration . (Sister projects there may also be of interest.)
