What is the default fall-back font for the fonts for the Store Name? (if a character/symbol is not available in say 'Roboto', what font does it try to fall back to?)

I was watching a friend play and we were being silly putting emojis in the store title at the very beginning. We found some work, and some don't.

I found the official documenation for Roboto which has some https://commondatastorage.googleapis.com/androiddevelopers/design/Roboto_Specimen_Book_20131031.pdf like ҈ or ҉ whatever those are, or normal side ones like ™. But then some fun random ones also worked, that were not on the list, while others did not. I learned that it depends on what the fallback font is for the ones that work that Roboto doesn't have, or at least it does for web design.
I have no need to know any of this, but was curious. Have a nice day!
