I would say this is a misunderstanding: The above example was meant for
pdfLaTeX not for XeLaTeX. 

There inputenc maps the û to a command (\^{u}), and t1enc.def then maps
it to char position 251, which in turn is mapped by the cmsuper fonts to
the glyph "ugrave" which can be copied without problems. 

An example for XeLaTeX would be:

\documentclass{article}
\usepackage{fontspec}

\begin{document}
\^{u} % copies badly 

\fontencoding{T1}\selectfont 
\^{u} % copies fine
\end{document}

So the problem is not the input but the output encoding: the default
encoding eu1 from fontspec doesn't contain the necessary commands to map
the commands like \^{u} to the correct single glyph "ugrave".

?? Not quite sure what this should mean.
