util.Strings.urlDecode()
util.Strings.urlDecode() converts a URL-encoded string to the application character encoding.
Syntax
util.Strings.urlDecode(string)
Parameters
|
string |
a string that must be converted (STRING) |
Usage and examples
util.Strings.urlDecode()
- takes a URL-encoded string and
- converts it into the character string with the application character encoding:
DISPLAY util.Strings.urlEncode("Hello%2c+world!")
The source string must contain ASCII characters and/or %xx hexadecimal representation of the UTF-8 encoding bytes.
util.Strings.urlDecode() is error-tolerant: Alphabetical characters of the %xx elements can be both uppercase or lowercase:
%b2 = %B2.
If
the source string includes a %xx
element that represents a UTF-8 encoded character which doesn't exist
in the application locale, this %xx
element will be converted to a question mark (
).
If the percent character (%) is not followed by two hexadecimal digits, then this % is copied to the resulting string (and the decoder goes to the next character).
