What is URL Encoding?
URL Encoding (or Percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be encoded. This includes spaces, special symbols, and non-ASCII characters.
Common Encoded Characters
| Character | Encoded (Percent) | Description |
|---|---|---|
| Space | %20 | Spaces are often converted to %20 or + |
| / | %2F | Forward slash (path separator) |
| ? | %3F | Question mark (starts query string) |
| & | %26 | Ampersand (separates parameters) |
| = | %3D | Equals sign (parameter value separator) |
