Just forwarding this LibreOffice bug report of mine here to ensure that
HB-NG doesn't make the same mistake. (I am not saying that it does, as a
I don't have any actual application using HB-NG in which to test.)
Or are such things out of the purview of HB?

Subject: Where to report a bug with Tamil text rendering in LibreOffice?

I am using LibreOffice 3.3.3 on Kubuntu Natty and 3.4.2 on Windows XP.
On both installations I observe the following bug:
In Tamil, vowelless consonants are considered independent grapheme
clusters on their own as they do not ligate with following consonants
unlike other Indic scripts. (The only exception is க் ligating with ஷ to
form க்ஷ.)
Take for example the Tamil word சித்திரை (name of a month). The grapheme
cluster split-out is: சி|த்|தி|ரை and not சி|த்தி|ரை. However, when my
cursor is to the left of த் and I press the right-cursor key, the cursor
moves to the right of தி, and vice versa with left-cursor key. Obviously
LibreOffice considers த்தி as a single cluster. Other applications (like
for example Thunderbird which I am using to compose this mail) correctly
treat த் and தி as separate grapheme clusters.
This faulty behaviour is seen for all CONSONANT + VIRAMA + CONSONANT
sequences in Tamil in LibreOffice.
Should I report this against LibreOffice in the FreeDesktop Bugzilla or
elsewhere against some other rendering library that LO uses?
