Hello dear Mojca, Let me mention one thing, while it is not too late ) I use not Termes, but standard Window Times New Roman. And I'd prefer italic latin letters to be taken from it, not from Termes. My working typescript: \starttypescript [serif] [TimesNR] \definefontsynonym [Serif] [times.ttf] [features=default] \definefontsynonym [SerifBold] [timesbd.ttf] [features=default] \definefontsynonym [SerifBoldItalic] [timesbi.ttf] [features=default] \definefontsynonym [SerifItalic] [timesi.ttf] [features=default] \definefontsynonym [SerifSlanted] [timesi.ttf] [features=default] \stoptypescript \starttypescript [math][TimesNR][all] \definefontsynonym[MathRoman][txmath@tx-math] \loadmapfile[original-youngryu-tx.map] \stoptypescript \starttypescript [TimesNR] \definetypeface [TimesNR] [rm] [serif] [TimesNR] [default] \definetypeface [TimesNR] [mm] [math] [TimesNR] [default] \stoptypescript \setupmathematics[lcgreek=normal, ucgreek=normal] \usetypescript[TimesNR] \setupbodyfontenvironment [11pt] [x=10pt] \setupbodyfont[TimesNR, 11pt]
