Run docker run --rm -v /home/runner/work/riscv-isa-manual/riscv-isa-manual:/build riscvintl/riscv-docs-base-container-image:latest \
  docker run --rm -v /home/runner/work/riscv-isa-manual/riscv-isa-manual:/build riscvintl/riscv-docs-base-container-image:latest \
  /bin/sh -c 'export LANG=C.utf8; cd ./build && make'
  shell: /usr/bin/bash -e {0}
