I'm using a TTF file that has no ligature capability as a built-in feature. It does however have glyphs for fi and fl but ConTeXt isn't substituting them.

So the question is: what do I need to do to persuade ConTeXt to do fi & fl ligature substitution?

Any suggestions please? Is a font features file the 'right' way? I would have thought that there was a more traditional solution you can write your own feature (examplex in test suite and manuals) where you map f + f onto ff

Thanks Hans - I keep forgetting about the test suite.

For the benefit of those coming here via the mail archive, I found what I needed in the cont-tst.zip test suite in the file fonts/extensions-001.tex http://www.pragma-ade.com/context/latest/cont-tst.zip

Now my problem is that the font only has ligatures for fi and fl which is making my life di-ffi-cult. <groan> Then forget abnout the ligatures ... these two were probably only added because of 'habbit'. Most people won't notice.
