OpenType ligatures

[Bertrand Bordage]

Hello,

I noticed LilyPond only support two text ligatures : fi and fl. Just as "Century Schoolbook".

I am using a font that support several ligatures : ſt, ct, Th, sp, etc.

For now I copy/paste when I meet these ligatures.

There is undoubtly a best way to achieve this, as fi & fl work. But I can't find how to do this. Few hours of code browsing hasn't helped.  :o(

Thanks,

Bertrand
