Maybe a workaround could be the Writer2LaTeX extension (http://writer2latex.sourceforge.net/), as it “converts documents into LaTeX 2e format for high quality typesetting”.
But it is cumbersome to use, as you have to install two packages on your system (LibreOffice and LaTeX).
Using Debian Lenny, OpenType fonts features (contextual alternates an ligatures) work.
It is a revolution. Simply put, LibreOffice suddenly became modern.
4.1 brings this to OS X with Core Text and to Linux with Pango/Harfbuzz.
…and windows XP ??? Left in the cold because it is old???
I have no idea about Windows XP specifically. What I do know is that, on Windows, the modern and “correct” way to implement OpenType is with Windows Presentation Foundation, which is a .NET technology. An alternate way of implementing OpenType is possible, but I am not aware of many applications that implement advanced OpenType features on Windows besides Adobe’s suite.
Well, there’s MS Office 2010 and 2013. And all browsers. And pretty much any application on a Mac, including LibreOffice.
Using Windows 10, when I use LibreOfficeDev 5.3.0 beta2, OpenType font features works for me.
I found some discussions here: Opentype features now enabled? Documentation?
