Also it's cleanrly not needed to duplicate Latin letters (or Cyrillic tool) to borrow them in them Tamil script, just in order to add Tamil vowel diacritics on top of them. If that proposer wnats to creatre a font allowing combinng Latin/Cyrillic letters with Tamil vowel signs, there's no need to duplicate the encoding of these base letters. Nothing prohibits a font to map those combinations, evne if it's not needed for other languages using the Latin and Cyrillic scripts: that could be done by extending an existing Tamil font (most of them already map Basic Latin, even if none of them currently map combinations with Tamil vowel signs). For the usage purpose desribed, in fact a good font for Latin and IPA would work, with just a few additions fow allowing the Tamil vowel signs. And no need to create specific encodings for Latin+generic diacritics, evne if the precombined letters are not encoded (why those additional "base letters" would be restricted to Tamil?) Given there's no user using this extended script, the Unicode policy will require first experimenting and creating a user community, and demonstrate that for this usage, the existing encodings cannot work reliably. But for now there's no need for it, no compatibility issues to resolve, no dictionaries or old books for which this encoding would be useful. And it's definitely not a problem of chicken and egg: this is an attempt to bypass the UCS encoding policies specifically for a script that really does not these duplicate extra base letters and combining vowels. And it's definitely not a new script by a proposed "new" script whose characters are in fact badly named! There's no such "Tamil-Latin" letters, but the real standard is about transliterations of Tamil using standard Latin letters (romanizations), or IPA symbols, and for that there are already standards that do not need any of these additions that would in fact add more complications and would solve no practical problems. Let's just focus on the Tamil romanization standards, and romanized IME for Tamil which already work as is.
