Hello Hans, as far as I remember this used to work once back in May in LuaTeX (because I was able to fake cacute in a font which didn't have it; however it never worked in XeTeX): \definefontsynonym[bla][Iwona-Regular] \definedfont[bla] \mainlanguage[sl] \starttext čšž (\textcaron)(\textacute)\crlf \quotation{this} is {\buildtextaccent\textacute c}\crlf \quotation{this} is {\buildtextaccent\textcaron c}\crlf \stoptext Now the characters don't compose any more. What's even more interesting, it fails badly with XeTeX, where most characters are simply blank. And even more interesting - watch the different guillemots when using LuaTeX and XeTeX. Even more interesting, if you use \definefontsynonym[bla][Iwona-Regular][encoding=uc] one gets different guillemots (it might be that they're taken from LM instead of Iwona when there is no [encoding=uc] present).
