The alphabet ${𝐅}_3+v{𝐅}_3$ where $v^2=1$ is viewed here as a quotient of the ring of integers of $𝐐\left(\sqrt{-2}\right)$ by the ideal (3). Self-dual ${𝐅}_3+v{𝐅}_3$ codes for the hermitian scalar product give $2$-modular lattices by construction $A_K$. There is a Gray map which maps self-dual codes for the Euclidean scalar product into Type III codes with a fixed point free involution in their automorphism group. Gleason type theorems for the symmetrized weight enumerators of Euclidean self-dual codes and the length weight enumerator of hermitian self-dual...
