ZO_SavedVars - account vs character behavior?

[Tazmyr]

Trying to understand the behavior and interaction between ZO_SavedVars:NewCharacterId() and ZO_SavedVars:NewAccountWide() ...

If I want to offer character-specific saved variables, would I call BOTH functions and then decide which set of variables to actually use?

If I do call BOTH, at save time, does the game save BOTH sets of variables?

Thanks!
