i wish i had some kind of tool that I could paste a unicode character into and it tells me which OSes and which versions of which OSes it will display on correctly. there's stuff like emojipedia but (1) that doesn't include non-emoji graphical characters like 🡅, and (2) it's harder to use becuase it focuses on "what does it look like" but I don't care what it looks like as long as it hasn't literally been decomposed into multiple characters
