Sorry, I replied prematurely. I did have to change my document to \documentclass{article}
\usepackage{fontspec} \usepackage{polyglossia} \setmainlanguage{Serbian} \usepackage{xunicode} \usepackage{xltxtra} \setmainfont[Script=Cyrillic,Language=Serbian]{Minion Pro} \begin{document} \fontsize{24}{24}\selectfont Убить! \end{document} to get the Serbian variant, and you're right. I've also tested it with a plain XeTeX variant: \font\samplefont = "Minion Pro:script=cyrl;language=SRB" at 72bp \samplefont \setbox0 \hbox{Убить!} \shipout\box0 \end The font has the kerning definition: @kc38_first_29 = [\uni040E \uni0423 \uni0474 ]; @kc38_second_16 = [\uni0435 \uni043E \uni0441 \uni0444 \uni0451 \uni0454 \uni0473 \uni0431.ital ]; pos @kc38_first_29 @kc38_second_16 -118; and the kerning pair in question is \uni0423\uni0431.ital So it should be kerned with the value -118. Unfortunately, it does seem like the rendered kerning value is deeper than that.
