I build the documentation in a Docker container, steered by release/doc/build-doc.sh and documented in the CG. It is veeery unlikely that there is anything to this theory.
Right.
I did a quick test with
\markup
$(markup-lambda (layout props arg) (markup?)
(let ((stil (interpret-markup layout props arg)))
(pretty-print (ly:stencil-expr stil))
stil))
\override #(quote ((font-encoding . fetaText)
(font-features . ("dlig"))))
{
"9" "9\\"
}
With official 2.24.0 binaries, I get
(utf-8-string
"emmentaler-20 7.029296875"
"9\\"
(translate-stencil

but when building inside the Docker container, I get

It seems that with the versions of Pango/Fontconfig in this Docker image,the backslash character, which doesn't exist in Emmentaler, causes a fallback
text font to be used, which obviously defeats the Emmentaler OTF feature that causes "9" and "\" to be combined specially.
