Character determines the representation?
Sorry, my mistake; what is more difficult is that the character is given by a locally summable function (not that the character determines the representation). Thanks for the reference and clarification.

Character determines the representation?
The theorem is proved in the book by HarishChandra and van Dijk, but only for linear groups. I'm not an expert in the padic case, but my vague recollection is there is a nontrivial technical issue towards the end that requires linearity. The proof in Jacquet Langlands is only for GL(2), at least as stated. Maybe an expert can enlighten us.

Yes, in the padic case, that is what I am saying. It is known over R.

Character determines the representation?
By reductive padic group you presumably mean an algebraic group, such as GL(n,F), Sp(2n,F), or SO(n,F), where the result holds. Maybe this is only a comment for the experts, but as far as I know, there is no proof in the literature if G is a nonlinear cover of such a group, and it might not be routine to prove this.

Does I belong to Weyl group?
Also I is in the Weyl group if and only if the center of the simply connected group is a 2group
