public class UTFEncodingUtil 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. Code is the public example given at http://www.w3.org/International/O-URL-code.html

Method Detail

encodeUTF8
public static java.lang.String encodeUTF8(java.lang.String s)
Encode a string according to RFC 1738."...Only alphanumerics [0-9a-zA-Z], the special characters "$-_.+!*'()," [not including the quotes - ed], and reserved characters used for their reserved purposes may be used unencoded within a URL."
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".
