public class URLUTF8Encoder

extends Object

Provides a method to encode any string into a URL-safe form, the so-called "x-www-form-urlencoded" form. Non-ASCII characters are first encoded as sequences of two or three bytes, using the UTF-8 algorithm, before being encoded in "x-www-form-urlencoded".

Method Summary

static String	decode(String s)
static String	encode(String s) Encode a string to the "x-www-form-urlencoded" form, enhanced with the UTF-8-in-URL proposal.

Method Detail

encode

public static String encode(String s)

Encode a string to the "x-www-form-urlencoded" form, enhanced with the UTF-8-in-URL proposal. This is what happens:

• The ASCII characters 'a' through 'z', 'A' through 'Z', and '0' through '9' remain the same.

• The space character ' ' is converted into a plus sign '+'.

• All other ASCII characters are converted into the 3-character string "%xy", where xy is the two-digit hexadecimal representation of the character code

• All non-ASCII characters are encoded in two steps: first to a sequence of 2 or 3 bytes, using the UTF-8 algorithm; secondly each of these bytes is encoded as "%xx".

Parameters:

s - The string to be encoded

Returns:

The encoded string

decode

public static String decode(String s)

Parameters:

s - the string to decode

Returns:

a decoded string

main

public static void main(String[] args)
