With pdflatex everything is fine.

Use \textcircumacute:
\documentclass[]{article}
\usepackage{fontspec}
\defaultfontfeatures{Ligatures=TeX}
\setmainfont{TeX Gyre Pagella}
\def\Thanh{H\`an~Th\textcircumacute{e}~Th\`anh}

thanks Ulrike, but this is not my point. I can also use
H\`an~Th^^^^1ebf~Th\`an
I want to know _why_ it works with the Type 1 but not with
the OpenType version of Pagella. It must be a problem with
the font or with fontspec.

Well if you push me so. Looking at the definition of \add@UTF@accent
in xunicode and wading through the \if-branches I would say the
reason is that if the argument of \' is \relax or a space the
command boils down to print only the "combining" char and no accent
at all. It looks like a bug to me. It works if I move the ending
#2\char"#1 to the end of the \if switches.
\documentclass{scrartcl}
\usepackage{fontspec}
\makeatletter
\gdef\add@UTF@accent#1#2#3{%
\ifx\relax#2\relax
\char"#3
\else
\ifx\ #2\relax
\char"#3
\else
\expandafter\ifx\UTF@space#2\relax
\char"#3
\else
\ifx~#2\char"#3\else
\char"#3
\fi
\fi
\fi
\fi#2\char"#1\relax} %#2\char"#1 moved

I *think* this is due to xunicode:
\documentclass{article}
\usepackage[EU1]{fontenc}
\providecommand{\UTFencname}{EU1}
\usepackage{xunicode}
\begin{document}
[\'x] [\'{}]
\end{document}
I'm not sure why this is happening, though; best to ask Ross Moore
about it, perhaps.
Cheers,
Will

Oops, I replied but didn't send this until now and I see that Ulrike
has delved into this in a proper amount of detail. Thanks! Has a bug
report been sent to Ross?
Cheers,
Will
