The radial glyph wave animation is also really cool, but the novelty will wear off and the delay will become grating especially if one is using the app in a utilitarian manner. Consider skipping transitions/animations if the user signals a preference for reduced/removed motion. Alternatively, you could add an on-page toggle for animations.
I made a similar tool that in my opinion is more useful for finding characters via drawings and similar characters. As you mentioned, the tool the OP posted seems cool for short periods of entertainment, but isn't very useful for utility. Link to the website here: https://unicode-atlas.vercel.app
I agree, you did a great job on the design, especially the border around the grid, I really like it. Also, just checked out your homepage, it looks really, really good
