I have been succesful in using the calrsfs package together with the standard CM type1cm font. I have been able to obtain in separate documents different calligraphic symbols in math mode with \mathcal{} for e.g. transform operators: \mathcal{F}, \mathcal{L}, ...

I am considering two different operators in one single document, with each the letter 'L' in calligraphic style, but in a different font.

I am working with MikTeX 2.8 / 2.9 and CM. I have considered What are all the font styles I can use in math mode? on this forum, as well as The LaTeX Companion.

The topic two fonts in math mode seems to offer the complete solution. However, where do I find the reference to the desired fonts ? The LaTeX Companion refers to nfssfont.tex. I would like to utilize the fourier math font.

  • Where do I find the reference to the fourier font in the command

    \DeclareSymbolFont{pazoletters}{OML}{zplm}{m}{it} 
    
  • I would like to utilize the fourier font to declare the first symbol with newcommand, then invoke the calrsfs package to have the second symbol in another font in calligraphic mode. Is it necessary to invoke the corresponding packages ?

    \usepackage{fourier} 
    \newcommand{\L_a}{\mathcal{L}
    
    \usepackage{calrsfs}    
    \newcommand{\L_b}{\mathcal{L}}
    

Once the font is in place with any of the previous method, declaring the new symbols is done with the \DeclareMathSymbol command (without declaring a complete new alphabet).

    \DeclareMathSymbol{\L_a}{12}{fourier}{"4C}
    \DeclareMathSymbol{\L_b}{12}{calrsfs}{"4C} 

Many thanks in advance,

Welcome to TeX.SX! You should also consider using the unicode-math package together with XeLaTeX or LuaLaTeX. You should highlight your code. –  canaaerus Aug 28 '12 at 6:51
    
@canaaerus : I really would like to compile with latex then ps2pdf. I'll have a look at unicode-math –  user18082 Aug 28 '12 at 7:45
    
One document I was looking for was the font encoding guide by Mittelbach et alia is.gd/vwlD1D –  user18082 Aug 28 '12 at 11:03

The calligraphic letters are in the OMS encoding

\documentclass{article}
\usepackage{calrsfs}
\DeclareMathAlphabet{\pazocal}{OMS}{zplm}{m}{n}
\newcommand{\La}{\mathcal{L}}
\newcommand{\Lb}{\pazocal{L}}
\begin{document}
$\La\Lb$
\end{document}
