I recently used hearts instead of bullet points in a post. I was then asked how I did that. So I thought I'd share.
I found this website several years ago https://fsymbols.com/keyboard/windows/alt-codes/list/ Your keyboard needs the Alt key to make this work. It has symbols, like hearts ♥ (alt 3), and "foreign" letters which come in handy, like é (alt 0233) and ö (alt 0246) plus other useful symbols like € (alt 0128) and £ (alt 156).
For us technologically challenged people, hold the Alt key down while typing the numbers.
