# Recognize this letter

Does anybody know how to make the following symbol in LaTeX? I think it is some calligraphic \mathcal{E}.

It is not anywhere in this table and online font recognizers do not recognize it.

The general font in the book I got this symbol from, Introduction to Quantum Optics by Grynberg, is not very extraordinary: this is a formula containing the strange symbol:

• If you can't find it in a font, you can always import it as a graphic and adapt it via tex.stackexchange.com/questions/224357/… – Steven B. Segletes Jun 23 '17 at 13:29
• Yes! Thats works, even in math mode. – Carucel Jun 23 '17 at 13:34
• A marginally close representation: (tug.dk/FontCatalogue/frenchcursive) via \documentclass{article} \usepackage[default]{frcursive} \usepackage[T1]{fontenc} \begin{document} E \end{document} – Steven B. Segletes Jun 23 '17 at 13:35
• I can't see that page online, but something similar to a normal \mathcal{D} is used in other notation in the book. It doesn't seem to use any unusual fonts on pages I can preview. – Chris H Jun 23 '17 at 13:58
• @samcarter -- that's the beast. you should post that as the answer. – barbara beeton Jun 23 '17 at 15:05

Online font matching sites suggests this symbol is from Linoscript font or Typo Upright font. I think it is the former, as the spiral in the lower part of the E is a bit different.

In the following image you can see an example of Linoscript (from https://www.linotype.com/45918/linoscript-product.html):

And of Typo Upright (from https://www.linotype.com/1086717/typo-upright-regular-product.html)

In case you have this font installed on your computer, you can use xelatex or lualatex in order to use the symbol in your document.

It also looks very much like TypoUpright BT (originally designed by Morris Fuller Benton in 1905 as a reproduction of the 19th century French Ronde), which can be obtained freely from myfontfree.

Here is a demo with xelatex:

    \documentclass[12pt]{article}
\usepackage{fontspec}
\pagestyle{empty}
\newfontfamily{\uprightcal}{TypoUpright BT}

\begin{document}%

Some text.

\Huge\uprightcal{E}

\end{document}
