      • detectOneOfCharacterEncodings

        public static com.ibm.icu.text.CharsetMatch detectOneOfCharacterEncodings​(byte[] value,
                                                                          java.lang.String characterEncoding)
        Detect the character encoding of value.
        Parameters:
        value - byte[] content to detect on
        characterEncoding - String character encoding to detect for
        Returns:
