Text notes, text areas, sheets are useless for non english users (JSON.encode can't correctly output UTF-8)#1263

JSON.encode can’t correctly output UTF-8.
I will use https://steamcommunity.com/sharedfiles/filedetails/?id=1124124634 as an example. After saving this list many Russian UPPERCASE characters become ?.

/execute print(JSON.encode("АБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯ"))

Here is my workaround of function updateSave(). Its saving values before encoding and after encoding replacing with them temporal setted values.
