Mapping Máaz: NASA Uses Navajo Language To Name Features On Mars - NPR
At the moment, Perseverance is working to learn more about a large rock named "Máaz" – Navajo for "Mars." .... But learning a new language can be tricky, even for robots. Perserverence's computers don't understand accent marks, so scientists have had to adapt.
So, UTF-8 is actually harder than rocket science. Who knew? Personally, I don't believe Perseverance will be able to succeed until it learns to speak like a native. It's time to send an upgrade to handle UTF-8.
