Minted escapeinside doesn't work within a string

Question

escapeinside=|| usually works but not inside what for my programming language (SAS) is a string:

\documentclass[a4paper,12pt]{book}
\usepackage{minted}
\usemintedstyle{vs}
\newcommand{\sasinline}[1]{\mintinline{sas}{#1}}
\newenvironment{sas}{\VerbatimEnvironment
  \begin{minted}[escapeinside=||]{sas}}
 {\end{minted}}

\begin{document} 

Is it possible to write \emph{percorso fisico} in italics here?
\begin{sas}
libname <|\emph{nome logico}|> '<|\emph{percorso fisico}|>' <|\emph{eventuali opzioni}|>;
\end{sas}

Leaving this as is:
\begin{sas}
libname corso '/projects/corsosas';
\end{sas}

\end{document}

Answer 1

An answer I know you will want to accept:

\documentclass[a4paper,12pt]{book}
\usepackage{minted}
\usemintedstyle{vs}
\newcommand{\sasinline}[1]{\mintinline{sas}{#1}}
\newenvironment{sas}{\VerbatimEnvironment
  \begin{minted}[escapeinside=||]{sas}}
 {\end{minted}}

\begin{document} 

Is it possible to write \emph{percorso fisico} in italics here?
\begin{sas}
libname <|\emph{nome logico}|> |\PYG{l+s}{\PYGZsq{}<}\PYG{l+s}{\emph{pineapple pizza}}\PYG{l+s}{>\PYGZsq{}}| <|\emph{eventuali opzioni}|>;
\end{sas}

Leaving this as is:
\begin{sas}
libname corso '/projects/corsosas';
\end{sas}

\end{document}
