Class URLUTF8Encoder


  • public class URLUTF8Encoder
    extends java.lang.Object
    Provides a method to encode any string into a URL-safe form. Non-ASCII characters are first encoded as sequences of two or three bytes, using the UTF-8 algorithm, before being encoded as %HH escapes.

      • encode

        public static java.lang.String encode​(java.lang.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.

        • 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
