Frequently Asked Questions
Does this encode the whole URL or just special characters in a component?
It performs component-level `encodeURIComponent`-style encoding, so reserved characters like `/`, `?`, and `&` inside a value get escaped - useful for query parameters and path segments.
What happens with spaces?
Spaces are converted to `%20`, matching standard URL percent-encoding rules.
Can I decode a URL that's only partially encoded?
Yes - decoding only affects recognized `%XX` sequences and leaves already-plain characters untouched.
