So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.

Steps

1. Install qemu-user-static (yay -S qemu-user-static).
   • This might need you to install pcre-static and update PGP keys (follow the tips in the comments here).
2. If not already present, install systemd-binfmt, the revamped version of binfmt-support tools
   • Your system has to support transparent Qemu user emulation, but fortunately, that is mostly enabled once the steps here have been followed.
3. Check the status of the systemd-binfmt unit (systemctl status systemd-binfmt) and (re)start if needed (sudo systemctl restart systemd-binfmt)
   • This unit has ARM support by default, but check the current documentation to make install it if needed
4. Mount the root partition of the ARM system into a folder (for e.g., sudo mount /dev/sdb2 arm_mountpoint)
5. Copy the QEMU ARM static binary (/usr/bin/qemu-arm-static on my distro) to the mounted root directory's usr/bin
