The following features have been added to the WhiteList for TextMeshPro in Build 1137.

I would like to see characterInfo (TMP_CharacterInfo) added here.

Currently I get an error when I try to access it in the indexer or get the Length.

Since characterInfo has vertex index, line number, display state, etc. for each character, it is useful when applying effects for each character.
