Fourier font and \textregistered symbol

I use TeXLive 2010 on Win XP and I notice that while the \textregistered symbol (an R in a circle which is normally placed next to trade names) appears well with the default CM font, it appears incorrectly with the fourier font (which I like much). Here's the code:

\documentclass[fleqn,a4paper,11pt]{article}
\usepackage[latin1]{inputenx}
\usepackage[T1]{fontenc}
\usepackage{fourier}

\begin{document}

Bananamark$^{{\scriptsize\mathrm{\textregistered}}{}}$

\end{document}


Any suggestion on how to make the \textregistered symbol appear well with the Fourier font?

You shouldn't ignore the log-file. LaTeX tells you

LaTeX Warning: Command \textregistered invalid in math mode on input line 10.


Use one of these:

Bananamark$^{\mbox{\scriptsize\textregistered}}$
Bananamark\textsuperscript{\textregistered}

%needs amsmath
Bananamark$^\text{\textregistered}$

Thanks for showing different ways of implementation. And 1 vote up. –  yCalleecharan Jul 12 '11 at 9:16

There's no need to use math mode (which results indeed in something wrong):

\textsuperscript{\textregistered}

Thanks and 1 vote up. I accept Ulrike's solution as it gives more possibilities. –  yCalleecharan Jul 12 '11 at 9:17
