[Tex/LaTex] French guillemets specific look

Question

I want to find the french guillemets in latex. To be honest I found them by many ways:

\og text \fg{}

with or without OT1 and french babel, but they do not produce the same result as those which can be seen here: www.phys.ens.fr/~dalibard/Notes_de_cours/X_MQ_2003.pdf on page 7

What do I have to typeset to get these ones?

Answer 1

The characters you're mentioning show that the document is using the obsolete package aeguill. If you really want to get that shape, you can load the necessary fonts and change the definition of \guillemotleft and \guillemotright to use wncyr; but be aware of the fact that you're using guillemets in Cyrillic style.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}

\frenchbsetup{og = «, fg = »}

\DeclareFontFamily{U}{wncyr}{}
\DeclareFontShape{U}{wncyr}{m}{n}{<->wncyr10}{}
\DeclareFontShape{U}{wncyr}{m}{it}{<->wncyi10}{}
\DeclareFontShape{U}{wncyr}{m}{sc}{<->wncysc10}{}
\DeclareFontShape{U}{wncyr}{b}{n}{<->wncyb10}{}

\DeclareTextCommand{\guillemotleft}{T1}{%
  {\fontencoding{U}\fontfamily{wncyr}\selectfont\symbol{"3C}}%
}
\DeclareTextCommand{\guillemotright}{T1}{%
  {\fontencoding{U}\fontfamily{wncyr}\selectfont\symbol{"3E}}%
}

\begin{document}

pourrait \og exister \fg{} se trouve

pourrait « exister » se trouve

\end{document}

Compare the output when the “normal” guillemets are used.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}

\frenchbsetup{og = «, fg = »}

\begin{document}

pourrait \og exister \fg{} se trouve

pourrait « exister » se trouve

\end{document}
