Different Style of pi infinity symbol

Question

Hi I am trying to create the following symbol in Latex. I am not able to make symbol of infinity to hang at the leg of pi as shown in symbol. The picture the I want is

But I got so far is the following.

The code I have so far is

\documentclass{article}
\usepackage{tikz}
\usepackage[outline]{contour}

\begin{document}
\scalebox{15} {
    \begin{tikzpicture}

 % \fill[blue!10!white] (-0.1,0) circle[radius=3.55mm];   

 \contourlength{0.05mm};

 \node (infinity) at (0.6mm,-0.1) {
                    \large\bf\color{blue!60!black}\contour{white}{$\infty$}};                   
 \contourlength{0.05mm};
  \node (pi) at (1mm,0) {
                    \LARGE\bf\color{blue!60!white}\contour{white}{$\pi$}};                                                                        
\end{tikzpicture}
}
\end{document}

Do you need this as a glyph or would a picture be acceptable? — samcarter_is_at_topanswers.xyz, Jun 01 '17 at 21:59
The \pi symbol you are using does not look like the one you want : its feet do not go back up. You should first find a suitable character. — marsupilam, Jun 01 '17 at 22:04
@Kumarm: ...then it's similar to the linked post as it's just like creating [a] logo with [a] fancy font. — Werner, Jun 01 '17 at 22:07
@marsupilam I noticed that. I tried to find that symbol as well but couln't. Can you please suggest me which package provide that character. — Kumarm, Jun 01 '17 at 22:07
@Kumarm I am looking as well. My best finds as of yet are \textpi from textgreek and \pi from upgreek. Maybe using fontspec ? — marsupilam, Jun 01 '17 at 22:10
@marsupilam with euler I get a different style of pi symbol which I dont like. Not luck with other suggestions. Thanks for trying though. — Kumarm, Jun 01 '17 at 22:26
An idea anyway : it would be easier to do what you want if instead of using the \infty glyph, you drew the actual lemniscate curve by parts (the below part then the \pi then close the lemniscate above it.) — marsupilam, Jun 01 '17 at 22:37
I voted to re-open as the main issue here is interleaving the characters which requires clipping or reconstruction of the paths before filling neither of which is addressed in the suggested duplicate. (@Werner) — David Carlisle, Jun 02 '17 at 06:25
@DavidCarlisle: Yet the accepted answer uses exactly the same technique as I suggest in the linked answer - Inkscape and export... A reference has been added, so one can close it as either. — Werner, Jun 02 '17 at 14:35

However, it relies on the use of the mathptmx (or equivalent) font.

\documentclass[10pt]{article}
\usepackage{xcolor,stackengine,trimclip,mathptmx}
\stackMath
\newcommand\mypi{\ensurestackMath{\stackengine{0pt}{%
  \stackengine{-1.97pt}{\color{cyan}\kern4.4pt\clipbox{4.4pt 0pt 0pt 0pt}
    {$\pi$}}{\scalebox{1.08}{$\scriptstyle\color{blue!80!black}\infty$}\mkern1.5mu}%
    {O}{c}{F}{F}{L}}{%
    \color{cyan}\clipbox{0pt 0pt 1.9pt 0pt}{$\pi$}\kern1.9pt}{O}{c}{F}{F}{L}%
}}
\begin{document}
\[x\mypi y\]
\end{document}

Awesome... Thanks. Can I position this according to my needs? – Kumarm Jun 01 '17 at 23:54
@Kumarm I edited it to make it a macro, so it can be used just like any other alphabetic math character. – Steven B. Segletes Jun 02 '17 at 00:37

Maybe you can use this conversion of your image to tikz:

Thank you very much. So you basically created both the symbol from scratch? — Kumarm, Jun 01 '17 at 22:55
@Kumarm Depends where and how you want to position it. I just took the infrastructure from your MWE to position it. — samcarter_is_at_topanswers.xyz, Jun 02 '17 at 08:33
