I read it but I missed the part that might explain that the virama
has a different nominal glyph (that thing that gets stuck on the
keyboard) for Devanangari and Tamil. It also has two different
actions in Devanagari and Tamil, creating conjunct consonants in the
one and consonant clusters in the other. This information must be
in Uniscribe since it is not in the encoding.
