I just switched from OS 10.9 to OS 10.14, and the character viewer (aka "Show Emoji & Symbols") looks like this:
Where have all the other Unicode blocks (e.g. Greek and Coptic, Cyrillic, Georgian, Phonetic Symbols) gone? How do I get them back?
(Also, what do I tag this as? keyboard and character are the only two suggestions, they don't seem appropriate, but I'm out of ideas…)
