Unit3d Ui text best fit and atlas overflow?

Question

Unity

I was only asked to google. I'll ask here just in case.

There was an issue with atlas overflow when rendering fonts with the best fit option . In the process of googling and reading the documentation, I came across an option that it would be good to call Font.RequestCharactersInTexture if it is necessary to show the text so that the atlas is redrawn when new characters appear that are not included in the current atlas by the textureRebuilt event . Did I understand correctly?
