Method Detail

encode

public static java.lang.String encode(java.lang.String unicode)

Convert a Unicode string, first to UTF-8 and then to an RFC 2396 compliant URI with optional fragment identifier using %NN escape mechanism as appropriate. The '%' character is assumed to already indicated an escape byte. The '%' character must be followed by two hexadecimal digits.

Parameters:

uri - The uri, in characters specified by RFC 2396 + '#'

Returns:

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.

Throws:

java.lang.IllegalArgumentException - If a % hex sequence is ill-formed.
