joaopaulo1511 said the following:
"I have been using Microsoft Office 2010 Technical Preview, and Word now 
supports the advanced OpenType properties (ligatures, contextual alternatives 
and so on). It would be nice to have them on OpenOffice.org too."

I second that wholeheartedly. Type foundries should start applying OpenType 
standard (2003) to their fonts.

MS Office 2010 does ligatures correctly. Notepad did it since 2006, Adobe since 
2004. I made a font with 400 (FOUR HUNDRED) plus ligatures and they form 
perfectly inside the browsers, Firefox, Safari, Lunascape and Arora plus Adobe 
InDesign and PhotoShop:

The font:
http://www.lovatasinhala.com/avazyabadu/samagana.ttf

The input is raw Latin letters within ISO-8859-1. All the ligatures are in the 
PUA of the font. I think OOw programmers should consult Mozilla on how they do 
this in Firefox and Thunderbird's mail editor. (IE makes the ligatures halfway 
and gives up and picks up again seeminlgy randomly. It is slow, and the letters 
are scratchy looking if you have Clear Type turned on, aaiyaiyaa! OOw is 
similar. Install my font and copy a para from the web site into OO-Write to see 
what I mean).

I use the following CSS3 rule in the web pages:
text-rendering: geometricPrecision / optimizeLegibility (both work)
I have no clue why it works except that the Lookup Tables in the font actually 
offer the ligatures. There is no problem in searching component letters 
embedded inside a ligature. (My base letters are, of course, awfully different 
from their common Latin shapes, sorry).

I have also extended JavaScript sort() to sort this text according to Sinhala 
(extended Sanskrit) collation order and it works perfectly in spite of ligaures.

There is one Unicode character that is suppoosed to be intervened between two 
letters when you do not want them to join: u200C called ZWNJ. I use that inside 
my web pages.

Thanks.
