Since some texts may end up being larger than the interface and not fit, like quest quest reward screen and other things, the game could cut the text a few words before reaching the end of the interface, and place three dots in the rest of the text’s place, upon passing the mouse over it, the game shows in a pop up near the mouse the full text.
In case this is used for items aswell, it would be necessary to make windows be a pop up to make it work,
since passing the mouse over the item icon and then removing would turn off the pop up, and also could turn into an annoyance for some players.
