I believe there is a ISO standard for doing this. Take a look at ISO 15919:2001 Saner explanation is at http://homepage.ntlworld.com/stone-catend/trind.htm :-) There is a thing which does this for Devanagari: https://www.dealloc.org/~mublin/iso15919.py.html However, this is not restricted to the 26 characters, but definitely less than 500 :-) -sdg- -- Sayamindu Dasgupta [http://sayamindu.randomink.org/ramblings] ------------------------------------------------------------------------------ Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
