Syntax

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

<Result>: Character string

Character string containing the encoded URL. The unauthorized characters are changed into %xx where xx is the hexadecimal value of this character.
This function returns no error code because all the character strings can be encoded.

<URL>: Character string (with quotes)

URL to encode (in ANSI format).

<Encoding format>: Optional Integer constant

Format for encoding the URL:
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 reserved characters of a URL are encoded in order to pass a URL in parameter to a URL.
Caution: The URL passed in parameter must have been encoded beforehand with one of the encodeURLFromAnsi or encodeURLFromUTF8 constants.

Remarks

Characters allowed in an encoded URL

The list of acceptable characters for an encoded URL is as follows:


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

According to the options, some of these characters can be encoded by the function.

Special cases

The encoding of an empty URL (empty string) is an empty URL.
Special case: the % sign and the + sign
- The % sign being used for the decimal encoding, this character is encoded in decimal as well.
- The "+" sign, which is an alternative to %20 for encoding a space, is also encoded (to avoid problems when decoding).
