我尝试将 RSFS 字体与 ConTeXt LMTX (2022.09.11 20:44) 一起使用，但没有任何效果。
从维基百科：
\starttypescript [math] [modern,computer-modern,latin-modern,ams] [size]
\definebodyfont [17.3pt,14.4pt,12pt,11pt,10pt,9pt][mm][mc=rsfs10 sa 1]
\definebodyfont [8pt,7pt] [mm] [mc=rsfs7 sa 1]
\definebodyfont [6pt,5pt,4pt] [mm] [mc=rsfs5 sa 1]
\stoptypescript
\definefamilysynonym [default] [scriptfamily] [mc]
\def\scr{\fam\purefamily{scriptfamily}} % To use ${\scr ABC}$
\def\script#1{{\scr#1}} % To use $\script{ABC}$
\definetypeface [modern] [mm] [math] [modern] [ams] [encoding=texnansi]
\setupbodyfont[reset,modern,11pt]
\starttext
${\scr ABCDEFGHIJKLMNOPQRSTUVWXYZ}$
$\sum_{\scr ABCDEFGHIJKLMNOPQRSTUVWXYZ}$
\stoptext
我收到此编译错误
tex error > tex error on line 7 in file ./main.tex: Undefined control sequence \undefined
<line 3.7>
\definefamilysynonym
[default] [scriptfamily] [mc]
...
7 >> \definefamilysynonym [default] [scriptfamily] [mc]
...
The control sequence at the end of the top line of your error message was never
\def'ed. You can just continue as I'll forget about whatever was undefined.
mtx-context | fatal error: return code: 1
由此SE 答案我收到以下错误：
tex error > tex error on line 35 in file ./main.tex: Undefined control sequence \undefined
<line 3.35>
\newfam
\calfam
...
35 >> \newfam\calfam

我检查了一下，没有找到有关 ConTeXt LMTX 中字体使用的任何较新的资源。
我需要做什么才能将 RSFS 字体添加到我的文档中？
