This is somewhat of a repost, but all the help I got did not really help. I am using Linux Libertine in LaTeX as my font in my thesis and I love every character except for the italic uppercase J. However, the uppercase J in mathmode is nice and I would like to replace the italic J with the mathmode J throughout the whole document. Is this possible? MWE:
\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{libertine}
\usepackage[libertine]{newtxmath}
\begin{document}
I do not like the italic \textit{J}, I want $J$ for that.
\end{document}
Output:
I know that mathmode J is produced by the newtxmath package, whereas the italic J is provided by the libertine package itself. I found several examples on how to redefine mathmode characters using \DeclareMathSymbol, but I only want to change textmode italic uppercase J to be the $J$.
Thank you in advance.
\newcommand? That would be a much simpler approach (at least, as far as I know, and I looked into similar stuff for my own thesis). However, that is best for stand-along things and may not do what you need if you sometimes have an italic uppercase J in part of a word.\newcommand? Also, this mainly concerns my Bibliography, in which many scientific Journals get abbreviated, e.g. J. Chem. Edu. The Bibliography is generated bynatbibfrom a.bibfile.\newcommand{\J}{$J$}into your preamble, then use it like this:\J. The bibliography wrinkle may make it more difficult, but you could try replacing the J in journal names with it. Note: if you want to use it as a stand-alone character (so there is a space after it), you will have to do\J{}. Otherwise the following space just gets consumed.
