[lltx] Italic correction

[Ulrike Fischer]

Hallo,


xetex and luatex have problems with the italic correction when they
use open type fonts. xetex seems to calculate at least in some
places an italic correction (but fails in the math too), in luatex
there is not italic correction at all. 

I found some old discussions in the xetex list but nothing really
decisive about if and how the problem should/will be solved. Does
someone here knows more about it?


\documentclass[12pt]{article}

\usepackage{fontspec}
\setmainfont{Times New Roman}
\makeatletter
\DeclareSymbolFont{letters}{\zf at enc}\rmdefault\mddefault\itdefault
%\DeclareSymbolFont{letters}{T1}{ptm}\mddefault\itdefault
\begin{document}

{\itshape f}( {\itshape f\/}(  \emph{f}(  \textit{f}( \textit{f\/}(

$f(a)$
\end{document}
