I want to save some strings.
But it show that data store only accept valid UTF-8 characters but no characters in the string is out of utf-8.
I think the 3 last characters seems not in the utf-8. Don’t know what replace with this.
Cause i have put just characters of Complete Character List for UTF-8

How are you creating the string that is being stored into the DataStore? Where does it come from? For example, does it come from a Luau string literal, or user input, etc.?
