Hi,
I just ran into something strange with ligature blocking:
---------------------------------------------------------------------------------------
\blockligatures[begrif:fl:ich]
\definefontfeature[default][default][dlig=yes,liga=yes,]
\definefontfeature[default:block][default][blockligatures=yes]
\definefontfamily[times][rm][Times New Roman]
\definefontfamily[termes[rm][TeX Gyre Termes]
\starttext
\switchtobodyfont[times]
\definedfont[Serif*default]
begrifflich
\blank
\definedfont[Serif*default:block]
begrifflich
\switchtobodyfont[termes]
\definedfont[Serif*default]
begrifflich
\blank
\definedfont[Serif*default:block]
begrifflich
\stoptext
---------------------------------------------------------------------------------------
With <Times New Roman> I'm getting < begriff|lich> when blockligatures is activated. Does anyone know what's going on there?
Best,
Denis

don't assume beforehand that something that doesn't work as expected is
a bug
the font just has no ligatures defined which you can remedy (in this
cae) with because it does have the glyphs
\startluacode
fonts.handlers.otf.addfeature {
name = "moreligatures",
type = "ligature",
data = {
['ff'] = { "f", "f" },
['fi'] = { "f", "i" },
['fl'] = { "f", "l" },
}
}
\stopluacode
\blockligatures[begrif:fl:ich]
\definefontfeature[default][default][dlig=yes,liga=yes,moreligatures=yes]
\definefontfamily[times][rm][Times New Roman]
\definefontfamily[termes[rm][TeX Gyre Termes]
\definefontfeature[default:block][default][blockligatures=yes]
\starttext
{\switchtobodyfont[times] \definedfont[Serif*default] begrifflich
ff fi fl\blank
\definedfont[Serif*default:block]
begrifflich ff fi fl\blank}
{\switchtobodyfont[termes]\definedfont[Serif*default] begrifflich
ff fi fl\blank
\definedfont[Serif*default:block]
begrifflich ff fi fl\blank}

Sorry, Hans, I didn't mean to be offensive.

I'm not sure I understand what is going on here. I thought \blockligatures simply means that instead of a ligature you'll have the regular glyphs in the output. Is that not correct?

it has more to do with searching for solutions using the subjects of
mail ... in which case 'bug' is not a good one

sure but times doesn't have these ligatures (it has the shapes but not
the features)
