[NTG-context] diacritics in Utopia/Fourier

I am running the latest version of ConTeXt and ran into a problem with some diacritical marks using %Fourier/Utopia Expert \usetypescript[type-syn] \usetypescript[fourier][\defaultencoding] \setupbodyfont[fourier,10.5pt] While \={\i} and \=a, for example, work as expected when the font is “italic” or bold, I get garbage when it is just roman. Is this a problem with the font encoding or is there something / different new that I must do to put macrons and so forth over letters in the roman typeface?
