If it is anything like described (7 bits for language, 5 bits for
consonant - clearly anti-Thai - because of links with Sri Lankan Buddhism? -
4 bits for vowel), it encodes Tamil as a C(V) syllabary, with the consonants
and vowels only available in the bits. To check how public the
documentation is, I've applied to join Yahoo group tune_rfc with the
"I heard on the Unicode mailing group that the definition of the TUNE
encoding was available here. I'd like to know what it is so I can check
that is as bad an idea as I think it is."
The number of codes needed matches the description - 25 by 16 codes.
(Plenty of gaps, I'm sure.)
This simplifies Tamil from level-2 to level-1 by changing from a character
encoding to an 'orthographic syllable' encoding.

I believe so.
By the way, why can't font-encoded Tamil (e.g. using ASCII codes as a hack)
display be handled on Windows by a GSUB table that handles the re-ordering?
Or would that make it Level-2 anyway? Where can I find a definition of
