When to use each scope

Component is the right choice for query-string values, path segments, and anything you plan to interpolate into a URL — it percent-encodes every reserved character including /, :, ?, &, and =.

Full URL preserves URL structure and only encodes unsafe characters (spaces, non-ASCII). Reach for it when you already have a valid URL and just need to make it safe to transmit.
