Thank you very much for your help. Since I do not have the OT fonts
I will try the first solution.<br>
<br>
Thanks again.<br>

Taking the symbol from txfonts it should be like this<br>

<div>The Type 1 Lucida fonts don't seem to have this symbol (which
would reside, I think, in lbme.pfb if it existed).</div>
<div><br>
</div>
<div>So the only solution based on them would be to fake the
symbol using \circlearrowleft and the code on the TeX FAQ for
the principal value integral at <<a moz-do-not-send="true"
href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=prinvalint">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=prinvalint</a>>,
yielding something like</div>
<div><br>
</div>
<div>\documentclass[12pt]{article}<br>
\usepackage[expert,lucidasmallscale]{lucidabr}<br>
\newcommand{\Xint}[1]{\mathchoice<br>
{\XXint\displaystyle\textstyle{#1}}%<br>
{\XXint\textstyle\scriptstyle{#1}}%<br>
{\XXint\scriptstyle\scriptscriptstyle{#1}}%<br>
{\XXint\scriptscriptstyle\scriptscriptstyle{#1}}%<br>
\!\int}<br>
\newcommand{\XXint}[3]{{\setbox0=\hbox{$#1{#2#3}{\int}$}<br>
\vbox{\hbox{$#2#3$}}\kern-.5\wd0}}<br>
\newcommand{\ointctrclockwise}{\Xint\circlearrowleft}<br>
\begin{document}<br>
\[ \ointctrclockwise_{\partial S} F \]<br>
\end{document}</div>
<div><br>
</div>
<div>But a more forward-looking solution would be to switch to
OpenType Lucida: the symbol is there in LucidaBrightMathOT.otf
in small, medium and large sizes, at U+2233 namely</div>
<div><br>
</div>
<div>0x110226 uni2233.ss03</div>
<div>0x11034f uni2233.mid</div>
<div>Ox110369 uni2233.display</div>
<div><br>
</div>
<div>What's needed is use the XeTeX or LuaTeX engines and the
fontspec and unicode-math LaTeX packages, yielding for example
(with XeLaTeX and the fonts installed at the OS level)</div>
<div><br>
</div>
<div>\documentclass[12pt]{article}</div>
<div>\usepackage{fontspec,unicode-math}<br>
\defaultfontfeatures{Ligatures=TeX,Scale=.92}<br>
\setmainfont{Lucida Bright OT}<br>
\setsansfont{Lucida Sans OT}<br>
\setmonofont{Lucida Sans Typewriter OT}<br>
\setmathfont{Lucida Bright Math OT}<br>
\begin{document}<br>
\[ \ointctrclockwise_{\partial S} F \]<br>
\end{document}</div>
<div><br>
</div>
<div>The results of the two approaches side-by-side are</div>
