URLs can only be sent over the internet using the ASCII character-set. URL encoding (also known as percent encoding) converts characters into a format that can be transmitted sent over the Internet - , using an a % followed by two hexadecimal digits. This ensures that URLs are properly formatted and can be interpreted correctly by web services.

For URLs, there are many reserved and common special characters:

• Reserved Characters: Characters with special meanings or functions in URLs are reserved. These include !, *, ', (, ), ;, :, @, &, =, $, ,, /, ?, #, [, ], and more.

• Unsafe Characters: Other characters outside of the ASCII character-set must be includedencoded, such as,", <, >, \, {, }, |, ^, ~, [ , ], `.

• Handling spaces: URLs cannot contain spaces: . When encoding whitespace characters you have two options:

  • Using %20 (percent encoding); or

  • Using + (for building query strings).
