Abstract: Let $ G$ be a semisimple almost simple algebraic group defined and split over a nonarchimedean local field $ K$ and let $ V$ be a unipotent representation of $ G(K)$ (for example, an Iwahori-spherical representation). We calculate the character of $ V$ at compact very regular elements of $ G(K)$.
