In the examples I mentioned (below), running ‘context’ on the first produces large colons, whereas ‘luatex’ on the second does not. The latter looks right to me. There is a similar issue with integral symbols, where somehow ConTeXt add additional spacing after it. http://www.ntg.nl/pipermail/ntg-context/2015/082541.html — context — \setupbodyfont[xits,10pt] \setupformulas[location=left] \begingroup\lccode`\~=`\:\lowercase{\endgroup \let~}\colon \mathcode`\:="8000 % \starttext The function $f: A → B$, $g\colon A → B$. \stoptext — — luatex — \begingroup\lccode`\~=`\:\lowercase{\endgroup \let~}\colon \mathcode`\:="8000 % The function $f: A \to B$. \end — ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : [email protected] / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
