Simply posting this made me commit to a human-readable translation.  Fully qualified emoji are difficult to code with.  You can, but most editors and operating systems get confused.  Ubuntu 22.04 can deal, particularly if you pin the font in Vim to a limited one like Bitstream Vera Sans, so the fallback is easy.  My latest version also uses a short UUID for the node ID, which isn't human readable, really, but any human-centric scheme, like incremental integers, has other problems.
