在“unicode-math”的范围选项中指定字符时，为什么替代数学样式字符也会被替换？

这在 XeLaTeX 和 LuaLaTeX 中都会发生，相关包的行为是unicode-math。Pagella Math 缺少一个\setminus符号，我用 Asana Math 的\setminus符号代替。但更多的是替换了 ；最明显的是scr和cal样式，这是意外行为。测试\sum，它似乎没有被替换，这是预期的行为。

是我遗漏了什么吗，还是这是包中的错误，或者是字体的 OpenType 行为中的错误？

我想我已经解决了这个问题，首先将 Pagella Math 指定为其数学运算符的数学字体，然后为其指定 Asana Math \setminus，最后再次指定 Pagella Math 以替换其数学样式版本，但我的问题仍然存在。

\documentclass{article}
%\usepackage{amsmath,amssymb}
\usepackage{fontspec}
\usepackage{unicode-math}

\setmathfont{texgyrepagella-math.otf}

% this line specifies to use \setminus from Asana-Math, but Asana-Math's special math styles are substituted as well; comment to void this behavior
\setmathfont[range={"29F5-"29F5}]{Asana-Math.otf}

% uncomment this line to substitute back Pagella Math's math styles while retaining math symbols
%\setmathfont[range={up,it,tt,bfup,bfit,bb,bbit,scr,,cal,bfcal,frak,bffrak,sfup,sfit,bfsfup,bfsfit}]{texgyrepagella-math.otf}

没有 Asana Math 线：缺少\setminus，Pagella 版本的\sum和scr 缺少 <code>\setminus</code>，Pagella 的 <code>\sum</code>，Pagella 的 <code>scr</code>

使用 Asana Math 行：Asana 的\setminus，Pagella 版本的\sum，Asana 版本的scr Asana 的 <code>\setminus</code>、Pagella 的 <code>\sum</code>、Asana 的 <code>scr</code>

答案1

这是 的范围处理中一个相当知名的错误 (?) unicode-math。诀窍是在所有其他范围之后再次加载主数学字体，并使用空范围。

\documentclass{article}
\usepackage{unicode-math}

\setmathfont{texgyrepagella-math.otf}
\setmathfont[range={\setminus}]{Asana-Math.otf}
\setmathfont[range={}]{texgyrepagella-math.otf}

\begin{document}

\(X\setminus Y\) and \(\sum a\).

\[ \symscr{ABCDEFGHIJKLMNOPQRSTUVWXYZ} \]

\end{document}
