僅對 \mathcal 和 \mathscr 使用 stix 字體

Question

如何限製stix字體包僅影響某些符號？就我而言，我只想更改與\mathcal{}和關聯的字體\mathscr{}。

人們必須去stix.sty提取相關資訊：

\documentclass{article}
\usepackage{amsmath}

\makeatletter
\DeclareFontEncoding{LS1}{}{}
\DeclareFontEncoding{LS2}{}{\noaccents@}
\DeclareFontSubstitution{LS1}{stix}{m}{n}
\DeclareFontSubstitution{LS2}{stix}{m}{n}
\makeatother

\DeclareMathAlphabet\mathscr{LS1}{stixscr}{m}{n}
\SetMathAlphabet\mathscr{bold}{LS1}{stixscr}{b}{n}
\DeclareMathAlphabet\mathcal{LS2}{stixcal}{m}{n}
\SetMathAlphabet\mathcal{bold}{LS2}{stixcal}{b}{n}

\begin{document}

This is \verb|\mathscr|: $\mathscr{A}\mathscr{B}$

This is \verb|\mathcal|: $\mathcal{A}\mathcal{B}$

\boldmath

This is \verb|\mathscr|: $\mathscr{A}\mathscr{B}$

This is \verb|\mathcal|: $\mathcal{A}\mathcal{B}$

\end{document}

輸出pdffonts：

GYLRUW+STIXMathScript-Bold           Type 1            yes yes no       8  0
UVZWHB+STIXMathCalligraphy-Bold      Type 1            yes yes no       9  0

用於比較

\documentclass{article}
\usepackage{amsmath}
\usepackage{mathrsfs}

\begin{document}

This is \verb|\mathscr|: $\mathscr{A}\mathscr{B}$

This is \verb|\mathcal|: $\mathcal{A}\mathcal{B}$

\boldmath

This is \verb|\mathscr|: $\mathscr{A}\mathscr{B}$

This is \verb|\mathcal|: $\mathcal{A}\mathcal{B}$

\end{document}
