Output

URL encoding (percent-encoding) converts special characters into a format safe for URLs, using % followed by two hex digits representing the character's ASCII value.

URLs can only contain certain ASCII characters (A-Z, a-z, 0-9, and some special characters). URL encoding allows safe transmission of spaces, symbols, and non-ASCII characters.

Spaces, most punctuation, and all non-ASCII characters should be encoded. Safe characters include A-Z, a-z, 0-9, and -_.~

%20 is the URL-encoded representation of a space character. It ensures URLs with spaces remain valid and properly interpreted.
