FAQ

What is component mode?

It encodes reserved characters like & and ? that would otherwise separate URL parts.

Why does decoding fail?

The input contains an invalid percent sequence such as a lone %.

Are query parameters parsed?

Yes, whenever the input is a complete valid URL.

Is anything logged?

No, processing is local.
