Frequently Asked Questions (FAQ)

URLs can only contain characters from the US-ASCII character set. Characters outside this set (like spaces, accented letters, and symbols like & or ?) must be encoded to prevent broken links.

encodeURI preserves protocol and domain syntax delimiters (like :, /, ?), while encodeURIComponent encodes all characters, making it ideal for query string parameters.
