I agree with Petr that the handling of italic correction at the end
of the math is a bit of a pain. It pops up in questions and
discussions regularly. As luatex inserts it only if a character
follows, we have experimented with zero width joiner and other
options but nothing looks really natural. Eg

\documentclass{article}
\usepackage{unicode-math}
\setmathfont{XITS Math}
\begin{document}
$\mathcal{P}x \mathcal{P}$x

$\mathcal{P}\strut x \mathcal{P}\Uchar"200D$x
\end{document}
