ISFOC is a standard from C-DAC (http://cdacindia.com). http://www.cdacindia.com/html/gist/standard/isfoc.asp ISFOC is a glyph-based standard, rather than a character-based standard -- thus side-stepping the various rendering issues discussed in the Unicode standard. The idea essentially is to avoid the huge-ligature-table problem in rendering Unicode encoded fonts, but instead standardize on a fixed set of pre-rendered glyph-pieces. This appears to be a custom solution and needs special case code like in devan-util.el, tamil-util.el to compose unicode characters by translation to sequences of ISFOC glyphs. - Hari -- Raja R Harinath ------------------------------ harinath@cs.umn.edu
