Puedes agregar manejadores de excepciones personalizados con <a href="https://www.starlette.dev/exceptions/" class="external-link" target="_blank">las mismas utilidades de excepciones de Starlette</a>.

Supongamos que tienes una excepción personalizada `UnicornException` que tú (o un paquete que usas) podrías lanzar.

Y quieres manejar esta excepción globalmente con FastAPI.
