Transliteration of Indic Scripts Implementation in ICU and Lessons Learned
Ram Viswanadha - IBM Corporation
This talk gives an overview and discusses the issues with transliteration of Indic scripts to Latin and between different Indic scripts, e.g: Devanagari-Telugu, Gujarati-Tamil, etc.
Different standards for transliterating between Indic Scripts and Latin are discussed and respective merits and disadvantages are highlighted.
It is often perceived that transliteration between different Indic scripts is straightforward because all Indic scripts have a common origin in Brahmi script.
The ISCII standard is based on this similarity between scripts, and the placement of Unicode code points for each Indic script is based on an early version of ISCII.
Correct transliteration between Indic scripts takes advantage of this allocation but handles special cases. The ICU implementation uses a script-neutral pivot range in Unicode. An online demonstration is presented.
