Frequently Asked Questions

What characters need to be URL-encoded?

Characters like spaces, &, =, ?, #, %, +, and non-ASCII characters must be encoded in URLs to avoid breaking the URL structure.

Difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URL (preserving ://?=&). encodeURIComponent encodes a component like a query string value (encodes everything including ?).

Is this the same as HTML entity encoding?

No. URL encoding uses percent-encoding (e.g., %20). HTML entity encoding uses & notation (e.g., &). Both are different contexts.
