\begin{document}
This is a sample document testing datatool's comparison
handlers. Note that UTF-8 characters are treated as two tokens
(the first and second octets) with regular (pdf)\LaTeX, so the
definition column on the following pages shows the two octets
for the UTF-8 character É as ÃĽ, which is how \LaTeX\ sees them. XeLaTeX will treat it as a single
token.
