This patch extends tcs(1) to understand TUNE.
http://www.tunerfc.tn.gov.in

TUNE is a 16 bit encoding scheme for Tamil.
Unlike Unicode, TUNE maps each character to a
single glyph.  This property of TUNE makes it
straight forward to view/edit Tamil in Plan 9.

Please use unicode.8.font from
http://www.tip9ug.jp/who/art/lib/font/madhavi.tgz
to view the Tamil glyphs in tune.c.

Sample text to test tune.c:
http://www.tip9ug.jp/who/art/lib/kp-tune.utf
http://www.tip9ug.jp/who/art/lib/kp-uni.utf

Pointers to TUNE and Unicode Tamil code charts are
available in the Links section in
http://www.tip9ug.jp/who/art/tamil

Please let me know if any other information is
needed.

Thanks.
