In this example \N{COMBINING CARON BELOW} looks bad -- a font problem ?
\usetypescript[libertine]
\setupbodyfont[libertine,rm,10pt]
\setupinterlinespace[line=2.6ex]
\starttext
%%echo '\N{LATIN SMALL LETTER A}\N{COMBINING DOT BELOW}\N{COMBINING
CARON BELOW}' |./uconv -t utf-8 -x "name-any
ạ̬
\stoptext
