To recreate:

Create new project
Add any variable set block with text input
Type in emoji(s)
Apply the block
Try to save the project

Expected behavior:
Project saves normally with "saved" message

Actual behavior:
Project doesn't save with invalid XML character

Edit: works only with variables

This seems new. I’ve been able to save with emoji. Can you share your browser version and perhaps the specific emoji?

Please try all emojis.

Works only with variables, edited original post.
