Chargement des fontes non-mathématiques

[kriztho]

Bonjour à tous,
Dans un document LaTeX est-il possible de connaître toutes les fontes chargées en plus de leur déclaration avec \usepackage{}.
Mon objectif est de savoir si une police ne possède pas les caractères mathématiques, quelle est la fonte qui est utilisée pour afficher ces caractères mathématiques.
Par exemple, si je déclare la fonte iwona dans le préambule, les équations mathématiques sont affichées avec une autre fonte, mais laquelle ?
Merci de votre aide.

Toutes les modifications sont dans le fichier .log ; par exemple, si on charge le package fourier :

On voit que toutes les "cm..." (Computer Modern) ont été remplacées par des "fut..." (Fourier).

Une autre façon de faire est de regarder les fichiers .sty et les changements qu'ils font, mais si un package fait appel à un package qui fait appel à un package... ce n'est pas toujours très clair.

Finalement, on peut aussi demander à Latex directement le nom des polices de maths :

Code : Tout sélectionner

\documentclass{article}

%\usepackage{lmodern}\usepackage{amsfonts}
\usepackage{fourier}
%\usepackage[charter]{mathdesign}
%\usepackage[utopia]{mathdesign}
%\usepackage[garamond]{mathdesign}
%\usepackage{txfonts}
%\usepackage{newtxtext,newtxmath}

\newcount\GMAthefam
\newcommand{\GuessMathAlphabetFont}[1]{%
    \ifdefined#1%
        $#1{\global\GMAthefam=\the\fam}$%\the\GMAthefam
        \texttt{\expandafter\meaning\the\textfont\GMAthefam}%
    \else
        \texttt{\csname@gobble\expandafter\endcsname\string#1 not defined}%
    \fi
}

\begin{document}

mathrm : \GuessMathAlphabetFont{\mathrm}

mathit : \GuessMathAlphabetFont{\mathit}

mathbf : \GuessMathAlphabetFont{\mathbf}

mathtt : \GuessMathAlphabetFont{\mathtt}

mathbb : \GuessMathAlphabetFont{\mathbb}

mathfrak : \GuessMathAlphabetFont{\mathfrak}

\end{document}

Pour \usepackage{fourier} on obtiendra :

qui permet de voir que les polices de maths sont désormais basées sur fourier (code "fut...") et pas sur Computer Modern (code "cm...").

C'est parfait pg, un très grand merci pour cette réponse technique et et très éclairante !
