- (hyphen or hyphen)

How does URL encoding work?

URI (Uniform Resource Identifier) ​​in some cases. Although commonly known as URL encoding, it is most commonly used in the core set of Uniform Resource Identifiers (URIs), which contain URLs and Uniform Resource Names (URNs). This inline URL encoding is also used to prepare data in HTTP requests and to represent HTML form data. Replaces all characters to be modified with a percent sign (%) and a two-digit hexadecimal value representing the corresponding ISO character set character.

Here are some examples:

$ (dollar sign) becomes %24

+ (plus sign) becomes %2B

(and) becomes %26

, (comma) becomes %2C

; (semicolon) becomes %3B

: (colon) becomes %3A

= (equal to) becomes%3D

 ? (question mark) becomes %3F

What types of URI characters are these?

Accepted characters in the URI are reserved or unreserved (or percent signs as part of the percent encoding). Reserved characters are characters that can have special meanings. A good example of this is the forward slash, which is often used to separate different parts of a URL. On the other hand, unreserved characters have no special meaning. When percent encoding is used, reserved characters are represented with a single character format. With each change in the specifications governing URIs and URI schemes, the set of reserved and non-reserved characters changes slightly, and the circumstances under which certain reserved characters have special meaning.
