I needed Unicode symbols for a story I’m working on. (I want to use them as “magic runes” so I could type them into a document, but without using the standard “runes” that are typically used.)
Shape Catcher let me draw what I was looking for and then get a list of Unicode characters that matched that drawing. It’s not exact so if there’s no perfect Unicode match, it will give you ones that are close. This actually turned out to my benefit as I found shapes I hadn’t considered but which worked nicely for my uses.
