使用 siunitx、fourier 和 amsmath 问题进行大胆数学运算

Question

通过这种配置，除了使用之外，我无法使用粗体 siunitx \pmb，但会产生丑陋的副作用：

\documentclass[margin=5pt]{standalone}

\usepackage{fourier}
\usepackage{fontspec}

\setmainfont{Erewhon}[
    Extension=.otf,
    UprightFont=*-Regular,
    ItalicFont=*-Italic,
    BoldFont=*-Bold,
    BoldItalicFont=*-BoldItalic,
    SlantedFont=*-RegularSlanted,
    BoldSlantedFont=*-BoldSlanted,
    SmallCapsFont=*-SmallCaps,
    SmallCapsFont=*-Regular,
    SmallCapsFeatures={Letters=SmallCaps}
    ]

\setsansfont{texgyreheros}[
    Scale=MatchLowercase,% or MatchUppercase
    Extension=.otf,
    UprightFont=*-regular,
    ItalicFont=*-italic,
    BoldFont=*-bold,
    BoldItalicFont=*-bolditalic,
    ]

\usepackage{amsmath,amsfonts,amssymb,mathrsfs}
\usepackage{bm}             % Bold math with \bm{}

\RequirePackage{siunitx} % \num{} ...

\sisetup{%
    unit-mode = text,%
%   detect-weight=true,
%   detect-family=true,
%   detect-inline-weight=math,
    locale=FR,%
    %detect-all,% Problème avec euro, inutile
    inter-unit-product = \ensuremath{{}\cdot{}},%
    group-minimum-digits=4,
    text-angstrom={Å},math-angstrom={\text{Å}}
} 


\begin{document}

$\pmb{\SI{2109}{kg}}$

\end{document}

Answer 1

使用[detect-all]选项siunitx然后

\let\svSI\SI
\renewcommand\SI[2][]{\bgroup\edef\tmpA{#1}\edef\tmpB{#2}\SIx}
\newcommand\SIx[2][]{%
  \textrm{\bfseries\boldmath\expandafter\svSI\expandafter[\tmpA]{\tmpB}[#1]{#2}}\egroup}

在序言中。已编辑以自动对粗体进行分组限制。已编辑以在数学和文本模式下工作。下面的 MWE 演示了修订后的所有可选参数均能\SI正常工作。

\documentclass[margin=5pt]{article}

\usepackage{fourier}
\usepackage{fontspec}

\setmainfont{Erewhon}[
    Extension=.otf,
    UprightFont=*-Regular,
    ItalicFont=*-Italic,

    BoldItalicFont=*-BoldItalic,
    SlantedFont=*-RegularSlanted,
    BoldSlantedFont=*-BoldSlanted,
    SmallCapsFont=*-SmallCaps,
    SmallCapsFont=*-Regular,
    SmallCapsFeatures={Letters=SmallCaps}
    ]

\setsansfont{texgyreheros}[
    Scale=MatchLowercase,% or MatchUppercase
    Extension=.otf,
    UprightFont=*-regular,
    ItalicFont=*-italic,
    BoldFont=*-bold,
    BoldItalicFont=*-bolditalic,
    ]

\usepackage{amsmath,amsfonts,amssymb,mathrsfs}
\usepackage{bm}             % Bold math with \bm{}

\RequirePackage[detect-all]{siunitx} % \num{} ...

} 

\let\svSI\SI
\renewcommand\SI[2][]{\bgroup\edef\tmpA{#1}\edef\tmpB{#2}\SIx}
\newcommand\SIx[2][]{%
  \textrm{\bfseries\boldmath\expandafter\svSI\expandafter[\tmpA]{\tmpB}[#1]{#2}}\egroup}
\begin{document}

Math mode: $\SI{2109}{kg}$

Text mode: \SI[per-mode=symbol]{2109}{\kg \per \s} not bold $xy$

Text mode: \SI[per-mode=fraction]{2109}[\$]{\kg \per \s} not bold $xy$
