My text isn't saving any changes
That means there's an issue with the encoding. To fix this issue it is recommended you delete the element and recreate it.
If there is a lot of content, copy the text into a plain text editor (for example, Notepad, or Wordpad) so you can paste it back in easily.
How do I add special characters?
There is not a built-in way to add special characters (superscripts and other symbols), but you can copy-paste them into the editor from an outside location.
How do I use my own fonts?
We unfortunately do not have a built-in way to add your own fonts.
