Method Detail

guessEncoding

public static java.lang.String guessEncoding(byte[] bytes,
                                             java.util.Map<DecodeHintType,?> hints)

Parameters:

bytes - bytes encoding a string, whose encoding should be guessed

hints - decode hints if applicable

Returns:

name of guessed encoding; at the moment will only guess one of: "SJIS", "UTF8", "ISO8859_1", or the platform default encoding if none of these can possibly be correct

guessCharset

public static java.nio.charset.Charset guessCharset(byte[] bytes,
                                                    java.util.Map<DecodeHintType,?> hints)

Parameters:

bytes - bytes encoding a string, whose encoding should be guessed

hints - decode hints if applicable

Returns:

Charset of guessed encoding; at the moment will only guess one of: SHIFT_JIS_CHARSET, StandardCharsets.UTF_8, StandardCharsets.ISO_8859_1, StandardCharsets.UTF_16, or the platform default encoding if none of these can possibly be correct
