In this example \N{COMBINING CARON BELOW} looks bad -- a font problem ?

Better in pure mkiv

\usetypescript[libertine]
\setupbodyfont[libertine,rm,10pt]
\setupinterlinespace[line=2.6ex]

\startluacode
function desc2utf8(desc)
    local us = ''
    local plane = 0
    for i,v in pairs(characters.data) do
      plane = i
      if v.description ==  desc then
       us = v.unicodeslot
       break
       end
    end
    return  tex.sprint(tex.ctxcatcodes,unicode.utf8.char(us))
end
\stopluacode
\def\N#1{\ctxlua{desc2utf8("#1")}}

\starttext
\N{LATIN SMALL LETTER A}\N{COMBINING DOT BELOW}\N{COMBINING CARON BELOW}
\stoptext
