FAQ

What is percent-encoding?

Percent-encoding is a mechanism for encoding information in a Uniform Resource Identifier (URI) by replacing reserved characters with a '%' followed by their two-digit hexadecimal representation.

Why should I encode spaces in URLs?

Spaces are not allowed in URLs. They are typically encoded as %20 or sometimes as a '+' depending on the context of the URL component.
