  The behavior of objects associated with general extended affine Lie algebras
is typically distinct from their counterparts in affine Lie algebras. Our
research focuses on studying characters and Cartan automorphisms, which appear
in the study of Chevalley involutions and Chevalley bases for extended affine
Lie algebras. We show that for almost all extended affine Lie algebras, any
finite order Cartan automorphism is diagonal, and its corresponding
combinatorial map is a character.
