I want to type in dʒ on macOS but I don't know how I can type it. I tried ⌥ + keys but it seems that none of the keys is mapped to the symbol. It's not listed on this page.
I use the US Extended keyboard: So how can I type this symbol?
If you know the Unicode name of the character, you can use ⌘ - ^ - Space to bring up a character search. This character is called Ezh:
Usually this is used for Emoji, but as you can see, it works for any character.
