possibly need a matching patch to icu like the (effectively forked) pango one of
http://cvs.gnome.org/viewcvs/pango/modules/indic/indic-ot.c?r1=1.16&r2=1.18

Comment 7 Caolan McNamara 2006-09-22 16:36:04 UTC
Got a fix for the batch listed in comment 1 which are ZWJ related 
but the batch in comment 3 still need more work

Comment 9 Caolan McNamara 2006-09-25 12:21:50 UTC
And the other issue is a difference in the state table for malayam in icu vs
pango, changing to the pango one gives (unsurprisingly) the same results for the
2nd batch.

(Additionally our OOo fontconfig fallback work needs to add some support in it's
glyph fallback to also include a trailing ZWJ in a glyph fallback block. this
will be in OOo 2.0.4-4.3, until then this can be tested by explictly using a
font which supports this characters, i.e. set the CTL font to lohit malayam
before typing the sequences)
