-fa 'Cascadia Code' → "xterm: no absolute path found for shell"

I have recently installed Cascadia Code (because I love its "4") and **I can use it in XTerm** $ xrdb -merge XTerm*faceName: Cascadia Code ^D $ **but**, otoh, if I try using the command line $ xterm -fa 'Cascadia Code' $ xterm: No absolute path found for shell: Code (above, the error message is printed after the prompt!). I know the Unix SE Q&A https://unix.stackexchange.com/questions/269351/xterm-no-absolute-path-found-for-shell , and I can understand the error message except that XTerm shouldn't look at Code in isolation. What I'm missing? --- As a follow up to a now deleted comment (ty Chris Davies) I tried xterm -fa 'Cascadia\ Code', xterm -fa 'Cascadia\\ Code', xterm -fa 'Cascadia\\\ Code', xterm -fa 'Cascadia\\\\ Code' to finally realize that any number of backslashes, it doesn't matter. --- I'm on Suse Tumbleweed, $ xterm -v $ XTerm(389) (also here the message is printed after the next prompt). Here it is the output of fc-list: $ fc-list 'Cascadia Code' /usr/share/fonts/texlive-cascadia-code/CascadiaCode-Italic.otf: Cascadia Code:style=Italic /usr/share/fonts/texlive-cascadia-code/CascadiaCode-SemiBoldItalic.otf: Cascadia Code,Cascadia Code SemiBold:style=SemiBold Italic,Italic /usr/share/fonts/texlive-cascadia-code/CascadiaCode-LightItalic.otf: Cascadia Code,Cascadia Code Light:style=Light Italic,Italic /usr/share/fonts/texlive-cascadia-code/CascadiaCode-SemiBold.otf: Cascadia Code,Cascadia Code SemiBold:style=SemiBold,Regular /usr/share/fonts/texlive-cascadia-code/CascadiaCode-SemiLight.otf: Cascadia Code,Cascadia Code SemiLight:style=SemiLight,Regular /usr/share/fonts/texlive-cascadia-code/CascadiaCode-Light.otf: Cascadia Code,Cascadia Code Light:style=Light,Regular /usr/share/fonts/texlive-cascadia-code/CascadiaCode-ExtraLight.otf: Cascadia Code,Cascadia Code ExtraLight:style=ExtraLight,Regular /usr/share/fonts/texlive-cascadia-code/CascadiaCode-ExtraLightItalic.otf: Cascadia Code,Cascadia Code ExtraLight:style=ExtraLight Italic,Italic /usr/share/fonts/texlive-cascadia-code/CascadiaCode-Bold.otf: Cascadia Code:style=Bold /usr/share/fonts/texlive-cascadia-code/CascadiaCode-BoldItalic.otf: Cascadia Code:style=Bold Italic /usr/share/fonts/texlive-cascadia-code/CascadiaCode-Regular.otf: Cascadia Code:style=Regular /usr/share/fonts/texlive-cascadia-code/CascadiaCode-SemiLightItalic.otf: Cascadia Code,Cascadia Code SemiLight:style=SemiLight Italic,Italic $
