Method Detail

escape

public static String escape(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 unreserved characters - _ . ! ~ * ' ( ) remain the same.
• 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
