When I combine fourier and other mathfont, there are some symbols not dislayed correctly. The operator "+" disappeared and the \left( \right) doesn't word. Is there any solution that I still can use those math fonts together. Thank you :)

\documentclass[12pt,oneside]{article} 
\usepackage{amsmath,amssymb,latexsym,amsfonts}
\usepackage{fourier}
\usepackage{pxfonts}
\begin{document}
Pxfonts along with fourier: $\left(\dfrac{x^2}{\sqrt{z+x}} \right)^2$
\end{document}
  • Why do you want to combine these two fonts? Are you aware of newpxmath and newpxtext? – Andrew Swann Jul 5 '15 at 8:20
  • Sorry, but it makes no sense loading pxfonts after fourier: at best you get Utopia as text font and a Palatino based math font, which are visually clashing. – egreg Jul 5 '15 at 9:56
  • how does this relate to your other question, Combine 2 math font together? there, you wanted fourier only for \wideOarc, and the technique for using only one or two symbols from that (or any different) font was correctly provided. – barbara beeton Jul 5 '15 at 12:27

Yes, you can get what you want, but I heartily discourage you from doing so.

The fourier package uses different font encodings for the math fonts, that it sets up at begin document, so after pxfonts has performed its duties: of course this utterly confuses math typesetting, because symbols will point to very different slots than expected by pxfonts.

The fourier package part related to text fonts is very easy and it boils down to

\renewcommand{\rmdefault}{futs} % Utopia as text font
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{fourier-orns}

Full example; note that the instruction for setting Utopia as text font must come after \usepackage{pxfonts}:

\documentclass[12pt,oneside]{article}
\usepackage{amsmath}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{fourier-orns}

\usepackage{pxfonts}
\renewcommand{\rmdefault}{futs}

\begin{document}

Pxfonts along with fourier: $\left(\dfrac{x^2}{\sqrt{z+x}} \right)^2$

Compare \textit{x} and $x$ or \textit{z} and $z$

\end{document}

enter image description here

My bet is that you just want Palatino for everything; then prefer \usepackage{newpxtext,newpxmath}:

\documentclass[12pt,oneside]{article} 
\usepackage{amsmath}
\usepackage{newpxtext,newpxmath}

\begin{document}

Pxfonts along with fourier: $\left(\dfrac{x^2}{\sqrt{z+x}} \right)^2$

Compare \textit{x} and $x$ or \textit{z} and $z$

\end{document}

enter image description here

I left the same text even if it states a falsity.

Note that in either case you shouldn't load amssymb and amsfonts (the former loads automatically the latter, by the way). You should never load latexsym that's only provided for compatibility with older documents.

  • Thank you for your help. I need to use fourier just because its \wideOarc :) – minmin Jul 5 '15 at 13:44
  • @minmin I suspected that the question was of the XY type. See also Importing a Single Symbol From a Different Font. If you are not able to import \wideOarc, please ask a question about it. – egreg Jul 5 '15 at 13:47
