One is that in ET-C (Extended Tamilconservative version), a character which has already been encoded, namely 0BB6 TAMILLETTER SHA, may need to take a different glyph from the standard one shown in the Unicodecode chart depending on the orthographic style of the user. The other is that in the sameET-C, the double avagraha (just a sequence of two avagraha-s) will need to be rendered as asingle glyph (by a ligature mechanism). I mention this here just to note that separatecharacters are not being encoded for these glyphic variations in Extended Tamil.§4. Variations in Extended TamilWe mentioned the two versions of Extended Tamil – liberal and conservative. (I hasten toremark that there are no political overtones here!) These terms merely refer to the extentto which the new Extended Tamil characters borrow glyphs from Grantha.The liberal version of Extended Tamil (“ET-L”) imports glyphs from Grantha for allthe new characters that need to be encoded for Extended Tamil. The glyphs were shown inthe table above. It also uses Grantha-style glyphs for consonants that carry Grantha-stylevowel signs, even if those consonants are already part of the Tamil script.5
