Or use hyperref:

\documentclass{article}
\let\OrgShow\show
\usepackage{ucs}
\AtBeginDocument{\let\show\OrgShow}
\usepackage[unicode]{hyperref}
\begin{document}
Hi
\pdfstringdef\ContentsString{Phrase Code = \textcopyright\texttrademark}
\pdfannot{%
  /Subtype/Square%
  /Border[0 0 .1]%
  /C[0 0 1]%
  /T(BoilerPlate)%
  /Contents(\ContentsString)%
}
\end{document}
