When should I use component mode?

Use component mode when encoding query parameters, form data, or any text that will be part of a URL component. It encodes more characters than standard URI encoding.

What is the difference between URI and URI component encoding?

URI encoding preserves URL structure characters like :, /, ?, # while URI component encoding treats these as data and encodes them. Use component encoding for parameters.

Why do some characters become %20, %21, etc.?

This is percent encoding where special characters are replaced with % followed by their hexadecimal ASCII code. %20 represents a space, %21 represents an exclamation mark.

Is URL encoding the same as HTML encoding?

No, URL encoding uses percent notation (%20 for space) while HTML encoding uses entities ( for space). They serve different purposes in web development.
