Hello shopsoup,
Thank you for reporting this issue. I apologize for the inconvenience you're experiencing with saving emojis in SP LMS EVENT articles.
To help me investigate this further, would you be willing to grant me temporary administrative access to your site? This will allow me to directly examine the problem and hopefully resolve it quickly.
Before providing credentials, I strongly advise creating a full backup of your site to ensure data security.
Looking forward to your response.
Best regards
