Frequently Asked Questions
What is the difference between the two modes?
Component mode encodes everything unsafe including / ? & = #, which is right for a single query value. Full-URL mode leaves those structural characters alone so the URL still works.
Why does a space become %20?
Because spaces are not allowed in a URL. %20 is the standard percent-encoded form. Form submissions historically use + instead, which is why both options exist.
How are non-English characters encoded?
They are converted to UTF-8 bytes first, then each byte is percent-encoded. The character é becomes %C3%A9 — two bytes, two escapes.
When must I encode an ampersand?
Whenever it is part of a value rather than a separator. A search for "Marks & Spencer" must send %26, or everything after the ampersand is read as a new parameter.
Input is processed in your browser and never transmitted. That said, treat any web page as untrusted for live production secrets — rotate anything you paste anywhere.
