HTML URL Encode

URL - Uniform Resource Locator

Web browsers request pages from web servers by using a URL.

A URL is the address of a web page, like: `https://www.google.com`

URL Encoding

URLs can only be sent over the Internet using the ASCII character-set.

Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format.

URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.

URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
