I am having a problem with kerning using fontspec in LuaLaTeX. I have posted about this [in StackExchange](http://tex.stackexchange.com/questions/41106/problem-with-kerning-using-lualatex), but didn't get any reply so far. Since then I tried making some changes to my file, and have come to believe that perhaps the issue has something to do with fontspec.

There is a screenshot [here](http://i.imgur.com/Sa7wi.jpg) showing the problem, which consists in the pair “AT” lacking kerning (in the output at the right, first and third lines; the other output is fine). On the left is the output without loading fontspec; on the right, with it. This is the code I used for the left output,

\documentclass{article}
%\usepackage{fontspec}
\begin{document}
\mbox{}\newline
\huge FOUNDATIONS\newline
\huge \textsc{foundations}\newline
\huge \textsc{\mbox{foundations}}
\end{document}
with the only change for the right one being uncommenting the second line.

Rendering with XeLaTeX does not reproduce the problem. Also, I don't know if it may be relevant, but loading `luaotfload` doesn't reproduce the problem either.
