Is this close enough?

\documentclass{article}
\usepackage{amsmath}

\begin{document}
    \[\mathcal{E} \varepsilon \]

[Tex/LaTex] Converting greek utf letters to latex symbols

In ConTeXt (both MkIV and MkII with utf-8 encoding), Greek letters work out of the box in text and math mode. (You need a text font with Greek letters)

\starttext
α $α$
\stoptext

With MkIV, Unicode characters behave like ASCII characters, so $\hat α$ is same as $\hat {α}$ . In MkII, you need to use the latter form.

You can create upside-down versions of \pi with the help of the \rotatebox and \reflectbox macros of the graphicx package. Two possibilities are shown in the following screenshot.

\documentclass{article}
\usepackage{graphicx} % provides "\rotatebox" and "\reflectbox" macros
\newcommand\rotpi{\rotatebox[origin=c]{180}{$\pi$}}
\newcommand\copi{\reflectbox{\rotpi}}
\begin{document} 
$\pi \rotpi \pi \copi $
\end{document}
