I had just tried to add a smiley face via cut-n-paste from https://getemoji.com/ but when I try to save the article I get the following error:
"Save failed with the following error: Incorrect string value: '\xF0\x9F\x98\x80"
I tried the same thing in my test cassiopea site and it worked fine so just wondering if it was specific to SP Page Builder v3 or Helix. i am using JCE as editor and it shows up fine in editor and preview windows.
Cheers
