# How to change calligraphic capital letters in mathpazo?

I'm trying to get the calligraphic capital "E". I really like mathpazo package but I'd like to change the way it renders calligraphic "E".

Below is a picture: when I type and compile $\mathcal{E}$ I get center version E, instead I'd like the left-most E.

When I didn't have mathpazo, I solved this problem by loading package mathalpha. I have posted below a MWE (also see this old question of mine):

\documentclass[a4paper, 12pt]{scrartcl}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}

%\usepackage[cm]{fullpage}
%\usepackage[top=2cm, bottom=3cm, right=2cm, left=3cm]{geometry}
\usepackage[math]{blindtext}
\usepackage[italian]{babel}
\usepackage{amsmath, amsfonts, amssymb}
\usepackage{empheq}
\usepackage{xfrac}
%\usepackage{mathpazo}
\usepackage[cal=boondoxo, calscaled=.98]{mathalfa}
\newcommand{\derivataparziale}[3]{\dfrac{\partial^{#1}{#2}}{\partial {#3}^{#1}} }

\begin{document}
$\mathcal{E}(y) = - \derivataparziale{}{V(y)}{y}$
\end{document}

Simply define bondoxo as mathscript:

\usepackage[scr=boondoxo, scrscaled=.98]{mathalfa}

and use it via \mathscr. This way you can use both fonts, if you wish.

Comment aside — the esdiff package makes it simpler to type partial derivatives, especially for crossed derivatives and specifying at which point the derivative is evaluated.

I wonder why it didn't take in \usepackage[cal=boondoxo, calscaled=.98]{mathalfa}, as written in my MWE, above. The solution you provided, ie. turning to \mathscr{E}, works. Mmm...who knows why? –  WobbyWindows Apr 19 at 14:47
I've just tested, and have no problem: it is boondoxothat appears as math calligraphic font. What happens to you is all the amore strange as I think mathpazodoesn't touch upon calligraphic fonts. Btw, I don't see why you scale boondoxo For me, no scaling is OK (checked with gsview). –  Bernard Apr 19 at 15:25
Thank you for your input on package esdiff, it's truly coming handy! Do you have any suggestion that might help with integrals too? For now, I'm going with \newcommand{\integrale}[4]{\displaystyle \int_{#3}^{#4} {#1} \,\text{d}{#2}}. Any suggestion is appreciated.;-) –  WobbyWindows Apr 23 at 17:43
Personally, I don't like very much this way of doing things, because it's a problem to share such files. In my opinion, it's more a question of setting up your editor. For instance, with my editor I could create a shortcut that inserts \int_{}^{*} * \d * with the cursor just between \{ and the following }. Another shortcut lets me go to the next *. –  Bernard Apr 23 at 18:09
Just out of curiosity, what editor are you using? What OS? –  WobbyWindows Apr 26 at 8:15

The BOONDOX font has the suitable interface:

\documentclass[a4paper, 12pt]{scrartcl}
\usepackage{amsmath}
\usepackage{mathpazo}
\usepackage{BOONDOX-cal}
\newcommand{\derivataparziale}[3]{\dfrac{\partial^{#1}{#2}}{\partial {#3}^{#1}} }

\begin{document}
$\mathcal{E}(y) = - \derivataparziale{}{V(y)}{y}$
\end{document}

Mmm...doesn't work for me! Tried looking in the package manager tlmgr --gui (under Linux)-- the only package I searched out is called boondox. When I compile I get an error that says: "Package textcomp Error: Symbol \textuparrow not provided by (textcomp) font family ppl in TS1 encoding. (textcomp) Default family used instead." –  WobbyWindows Apr 19 at 14:35
@WobbyWindows You have an outdated TeX distribution. –  egreg Apr 19 at 14:38
Don't know why, but your MWE's working on my system. Just wanted to let you know. –  WobbyWindows May 9 at 18:12
