No a bad idea to me. I actually thought to make a logging wrapper for representing hex-encoded strings in terminal with emojis. You know, just for debugging things.

I mean ... this could be done unironically. We'd just have to agree on a standard as a community, idk if unicode to bytes is enough here

But idk how many people on this world use a smartphone, can deal with numbers but aren't literate. Maybe that is just my ignorance ... aren't literacy and basic maths related (I genuienly don't know)

Something close to this exists and have been implemented in some DeFi wallets, Argent for instance, which uses emojis for security verification:

Why not, if it can increase usability...
