Frequently Asked Questions

Why do I need to encode URLs?

URLs can only contain specific ASCII characters. Special characters (like spaces or non-English letters) must be percent-encoded to prevent browsers from misinterpreting URL structures.

What is percent-encoding?

Percent-encoding replaces unsafe characters with a percent sign (%) followed by a two-digit hexadecimal number representing the character's ASCII value (e.g. a space becomes `%20`).

What is the difference between encodeURI and encodeURIComponent?

`encodeURI` is used to encode a full URL, leaving path separators (like `/` and `?`) intact. `encodeURIComponent` encodes all special characters, making it ideal for encoding query parameters.
