There are 155,063 Unicode characters. A lot of that is stuff from other languages, but there is still a large amount of randomly useful characters like arrows and symbols and whatnot. There are so many that even if you find good lists, it’s hard to search and sort. I like Benjamin Milde’s idea, shapecatcher, that lets you draw what you want and tries to find it for you.
Need an arrow that points up and to the left, that also has a circle around it? I actually assumed there wasn’t one, but there totally is.
