URL Encoding and Decoding

URL encoding is a mechanism for translating special characters and symbols into a format that can be safely transmitted over the Internet. This process ensures that URLs and data remain valid and secure across different systems and browsers.

Why URL Encoding is Important

URLs can only use ASCII characters, but often need to handle:

  • Special characters (like spaces, &, ?, etc.)
  • Non-ASCII characters (like é, ñ, 漢字)
  • Reserved characters in URLs
  • Unsafe characters that could be misinterpreted

How It Works

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

  • Space becomes either "%20" or "+" (in forms)
  • ! becomes "%21"
  • @ becomes "%40"
  • é becomes "%C3%A9"
