- The corresponding Unicode String

decode
public static java.lang.String decode(java.lang.String uri)
Convert a URI, in US-ASCII, with escaped characters taken from UTF-8, to the corresponding Unicode string. On ill-formed input the results are undefined, specifically if the unescaped version is not a UTF-8 String, some String will be returned. Escaped '%' characters (i.e. "%25") are left unchanged.- Parameters:
uri
- The uri, in characters specified by RFC 2396 + '#'.- Returns:
- The corresponding Unicode String.
