\documentclass{article}
\usepackage[utopia]{mathdesign}
\usepackage{xltxtra}
\setmainfont{Arial}%to better see the differences
\catcode`\×=\active
\def×{\ifmmode\times\else\char"00D7\fi}
\catcode`\±=\active
\def±{\ifmmode\pm\else\char"00B1\fi}

\begin{document}\pagestyle{empty}
text ×±

math $×±$
\end{document}
