encodeUTF8

public static String encodeUTF8(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".

Parameters:
s - The string to be encoded
Returns:
The encoded string
