## Idea

The ordinary Chern character for K-theory sends K-classes to ordinary cohomology with real coefficients. Over a smooth manifold the de Rham theorem makes this equivalently take values in de Rham cohomology.

The twisted Chern character analogously goes from twisted K-theory to twisted de Rham cohomology.
