Hello all,

I am developing a Malayalam font for use in OpenOffice.org 1.1.3 and KDE. This 
font also includes latin characters and diacritical marks for the purpose of 
indic transliteration. The problem is, I need 2 characters (glyphs) which are

latin small l with macron and macron below, and 
latin small l with diaeresis below

which are not available as precomposed forms in the Latin and IPA blocks in 
Unicode (all the rest are available).

Due to this, I have to use open type positioning features in the font for 
these characters. Unfortunately, Openoffice.org doesn't render the 
positioning properly, and instead, displays the base character and the mark 
as if they were 2 characters (ie, one after the another).

How does Openoffice do the shaping of latin with diacritical marks ? Does it 
use the GPOS tables in open type fonts ?

In Qt, Latin diacritical marks are rendered using a heuristic, which allows 
the positioning of the marks (although not very accurately) without the use 
of anchors. However, this seems not to be implemented in OOo.
