Yes, I used "apt .../stable", and it was 9.53.3~dfsg-7 that was
fetched, not the security update.
zira:~> apt-show-versions -a ghostscript
ghostscript:amd64 9.54.0~dfsg-5 install ok installed
ghostscript:amd64 9.53.3~dfsg-7 stable ftp.debian.org
ghostscript:amd64 9.53.3~dfsg-7+deb11u1 stable-security security.debian.org
No stable-updates version
ghostscript:amd64 9.54.0~dfsg-5 testing ftp.debian.org
ghostscript:amd64 9.54.0~dfsg-5 unstable ftp.debian.org
ghostscript:amd64 9.55.0~~rc1~dfsg-1 experimental ftp.debian.org
ghostscript:amd64/testing 9.54.0~dfsg-5 uptodate
Perhaps I should have used "/stable-security".

Anyway, I doubt that this is related to the font / mapping issue.
