I'm a bit ashamed to say that, after using various ASCII symbols (for progress, checkmarks etc.) in the 90s and early 2000s, when I first discovered we can actually put special Unicode characters on the terminal and it will be rendered almost universally in a similar way, it was like discovering an unknown land.

While rockets and hearts seem more like unnecessary abuse, there are a few icons that really make sense in CLI and TUI programs, but now I'm hesitant to use them as then people who don't know me get suspicious it could be AI slop.
