      • stringToUtf8Bytes

        public static byte[] stringToUtf8Bytes​(java.lang.String string)
        Converts a string into its Java-style UTF-8 form. Java-style UTF-8 differs from normal UTF-8 in the handling of character '\0' and surrogate pairs.
        Parameters:
        string - non-null; the string to convert
        Returns:
        non-null; the UTF-8 bytes for it

      • utf8BytesToString

        public static java.lang.String utf8BytesToString​(byte[] bytes,
                                                 int start,
                                                 int length)
        Converts an array of UTF-8 bytes into a string.

        This method uses a global buffer to avoid having to allocate one every time, so it is *not* thread-safe

        Parameters:
        bytes - non-null; the bytes to convert
        start - the start index of the utf8 string to convert
        length - the length of the utf8 string to convert, not including any null-terminator that might be present
        Returns:
        non-null; the converted string

                             throws java.io.IOException
        Throws:
