OK, thank you for your reply. My need is to access a symbol for the
contour integral with <br>
counterclockwise orientation. Something like \oint but with an arrow
on the circle.<br>
Taking the symbol from txfonts it should be like this<br>
<br>
<img style="vertical-align: middle"
src="cid:part1.06020304.07000409@gmail.com"
alt="$\displaystyle\varointctrclockwise_{\partial S} F$"><br>
<br>
(the code above was $\displaystyle\varointctrclockwise_{\partial S}
F$)<br>
Is such a symbol available in Lucida?<br>
<br>
thank you,<br>
<br>
Antonis.<br>

I have the Y&Y version. The font lbmi.pfb contains several integrals at
positions
U+222C to U+2232. How do I access them?
The first two are OK. They are \iint and \iiint. The fourth is \surfint
but what about the rest?

These integral signs are of smaller size than the usual integrals signs, i.e. they are of the size of letters, not big operators.
This seems the reason why they've never been used, except in the original Y&Y plain TeX macro file, lcdplain.tex, which included definitions for them but commented those definitions out. And AFAIK it's never been retained for the LaTeX support packages.
Namely, lcdplain.tex contained
% Various types of small integrals
% \mathchardef\dblint="0188
% \mathchardef\trplint="0189
% \mathchardef\contint="018A
% \mathchardef\surfint="018B
% \mathchardef\volint="018C
% \mathchardef\clwint="018D
% \mathchardef\cclwcint="018E
% \mathchardef\clwcint="018F
In LaTeX you would get the same with
\DeclareMathSymbol{\dblint}{\mathord}{letters}{136}
\DeclareMathSymbol{\trplint}{\mathord}{letters}{137}
\DeclareMathSymbol{\contint}{\mathord}{letters}{138}
\DeclareMathSymbol{\varsurfint}{\mathord}{letters}{139}
\DeclareMathSymbol{\volint}{\mathord}{letters}{140}
\DeclareMathSymbol{\clwint}{\mathord}{letters}{141}
\DeclareMathSymbol{\cclwcint}{\mathord}{letters}{142}Bruno Voisin <a class="moz-txt-link-rfc2396E" href="mailto:bvoisin@me.com"><bvoisin@me.com></a>
\DeclareMathSymbol{\clwcint}{\mathord}{letters}{143}
(with a name change to avoid a clash with the existing definition of \surfint).
By the way, you wouldn't get these with \iint, \iiint and \surfint, which are constructed differently and (I think) grow with content.
Hope this helps,
Bruno Voisin
