Keyboard and emoji viewer - issue

Good evening,

it's not in the application shortcut preferences that you find anything related to the emoji keyboard..

However, by checking this box:



we get this:



or another option:


Best regards.

to better explain :)

Hello,

OK -
Your first screenshot showed a search for emojis in the "Application Shortcuts" window..., which is what surprised me...

That said, your issue is indeed strange. I see that in Chrome (which I don't use), you have this option at the bottom of the "Edit" menu. Usually, this choice is in the bottom of the "Edit" menu.
Just for testing, what happens if you try the same thing from another application, for example TextEdit?

In any case, that doesn't explain why your system doesn't keep the checkbox checked in the system preferences. We can also see that your menu bar shows a flag where you choose your keyboard, while when the checkbox for displaying the keyboard viewer is checked, we should see what I showed above... so indeed, that's not correct.

Maybe a bug in OS X 10.13.3? I had installed it, then reverted to OS X 10.12.6 due to various bugs. However, I re-installed it on an external disk for testing, and as soon as I have a moment, I will test it after booting my Mac from that external disk.

In the meantime, try booting the Mac from the recovery partition and performing a system repair.

EDIT: I just tested it on OS X 10.13.3, and I had no issues opening and using this emoji palette.

Just in case, can you check if you see this in the "Font Book" application:



?

Good evening, thank you very much for the explanations.

Actually, I tried to clear the caches using CleanMyMac 3. The emoji function worked well in the end. The problem is that the shortcut (^Command Space) doesn't work to open emojis. So I checked in System > Keyboard > Shortcuts, and I found that the shortcut no longer exists.

I decided to reset macOS (Command + R) at startup, and macOS High Sierra 10.13.3 was reinstalled (it's the same version I had before). This time I checked the shortcut (^Command Space) but once again it doesn't work, whereas if I click on Edit > Emoji and Symbols, it works.

Another thing, the option to Show Viewers works just fine :)
