Usage and safety notes

When to encode a component

Encode a single path segment or parameter value; for example a/b becomes a%2Fb。

Repeated parameters are preserved

Parsing and building preserve repeated parameters in order, such as tag=one&tag=。

Inspect redirect targets

Encoding is not a security check. Verify the scheme and host before opening an untrusted link.
