Symbol: ♥Heart

♥♥♥♥♥
The heart symbol shows up on custom license plates as a cute little allowance in the otherwise-bureaucratic DMV system. It’s definitely the most common of the non-alphanumeric characters I see on license plates. People use it to stand in for words like love, heart, fan (like, I’m a fan of), and others depending on the context. Most states maintain a whitelist of symbols they know how to print, track, and police for content, and heart made the cut because it’s pretty harmless and hard to turn into anything offensive. It also doesn’t confuse toll readers or law enforcement databases. Love is officially IN the system.
