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
Got a fix for the batch listed in comment 1 which are ZWJ related but the batch in comment 3 still need more work
Created attachment 137045 [details] patch to fix against icu
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)
