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

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}
\stoptext
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?
sure but times doesn't have these ligatures (it has the shapes but not
it has more to do with searching for solutions using the subjects of 
mail ... in which case 'bug' is not a good one

the features)
