I had misunderstood you and was trying with -nographic earlier :) .
Found an easier way to reproduce:
qemu-system-aarch64 \
-display gtk -enable-kvm -machine virt -cpu host -m 1G -smp 2 \
-kernel /boot/vmlinuz -initrd /boot/initrd.img \
-append "break console=ttyAMA0"
Then, run cat on the initramfs shell and see arrow keys result in ^[ .
For x86_64, it's console=ttyS0 and ^[[A etc. as you also found out.
