\usepackage{cochineal}
我有一个用和排版的文本和数学文档\usepackage[cochineal]{newtxmath}
。
我想使用该cochineal
字体来表示文本和数学,但要替换希腊数学字体仅有的,来自usepackage[libertine]{newtxmath}
。我尝试了以下操作(根据此答案:将数学字体更改为希腊字母),但没有成功。
\documentclass[10pt,a4paper]{article}
\usepackage{cochineal}
\usepackage{textcomp}
\usepackage[cochineal]{newtxmath}
\usepackage[T1]{fontenc}
\DeclareSymbolFont{Letters} {OML}{libertine}{m}{n} %% how to access the [libertine]{newtxmath} here?
\DeclareMathSymbol\Gamma {\mathalpha}{Letters}{"00}
\DeclareMathSymbol\Delta {\mathalpha}{Letters}{"01}
% etc
\DeclareMathSymbol{\alpha} {\mathalpha}{Letters}{"0B}
\DeclareMathSymbol{\beta} {\mathalpha}{Letters}{"0C}
% etc
\begin{document}
$\alpha, \beta$
\end{document}
答案1
在您的示例中,您没有使用正确的 Libertine 字体编码。
以下是使用 Cochineal 和 Libertine 的希腊字母的示例。声明希腊字母的代码基于 的newtxmath
代码。

为了进行比较,这里有相同的例子,但没有希腊字母的新定义。
\documentclass{article}
\usepackage{cochineal}
\usepackage[cochineal]{newtxmath}

\[

答案2
unicode-math
如果您在 LuaLaTeX 或 XeLaTeX 中使用,或者在 XeLaTeX 中使用,这会容易得多。mathspec
前者允许您使用 \setmathfont[range=it/{greek,Greek}, Scale=MatchLowercase]{Libertinus Math}
,后者 允许您使用\setmathsfont(Greek){Libertinus}
。
有些出版商在 2020 年仍强迫您使用传统的 8 位字体,但我的建议是,unicode-math
在可以的情况下使用 LuaLaTeX,在必须的情况下使用 PDFTeX。
