  "abstract": "We show that the angular structure of the leading radiation around a bound state in the continuum (BIC) directly encodes its topology. This angular information can be determined from the BIC itself and used to design prescribed topological polarization textures. As examples, we identify BICs carrying high topological charges $q=4$ and $q=-5$ in $C_{6v}$ photonic crystal slabs, addressing the question of whether high-charge BICs exist and how they can be systematically realized. We further show that zeros of the leading radiation can drive both topological transitions and the bifurcation of new BIC families. These findings may enable new approaches to polarization engineering in structured light and resonant photonics.",
