Syntax

<Result> = URLEncode(<URL> [, <Encoding format>])

<Result>: Character string

Character string containing the encoded URL. Non-allowed characters are changed to %xx, where xx is the hexadecimal value of this character.
This function returns no error code because all character strings can be encoded.

<URL>: Character string

URL to be encoded (in ANSI format).

<Encoding format>: Optional Integer constant

Versions 22 and later
URL encoding format:
encodeURLFromAnsi URL format. The encoded text only contains characters allowed in a URL. The text to encode is an ANSI string.
encodeURLFromUTF8
(Default value) URL format. The encoded text only contains characters allowed in a URL. The text to encode is a UTF-8 string.
encodeURLParameter URL format. The specific characters of a URL are encoded to pass a URL as a parameter to another URL.
Caution: The URL passed as parameter must have been encoded with the encodeURLFromAnsi or encodeURLFromUTF8 constant.

This parameter is not available.

Remarks

Characters allowed in an encoded URL

The list of characters allowed in an encoded URL is as follows:


;	/	?	:	@
&	=	+	$	,
-	_	.	!	~
*	'	(	\|	)
%	#	digits	letters (uppercase and lowercase characters)

According to the options, the function will be able to encode some of these characters.

Special cases

Encoding an empty URL (empty string) returns an empty URL.
Special case: the "%" and "+" signs
- Since the % sign is used for decimal encoding, it is itself encoded as a decimal.
- The "+" sign, which is an alternative to %20 for encoding a space, is also encoded (to avoid problems when decoding).
