        +
        Encodes the given optional String into a variable amount of bytes. The + amount written can be determined by calling + calculateEncodedStringLength. +

        + Strings are encoded in a fashion similar to UTF-8, in that ASCII + characters are written in one byte. This encoding is more efficient than + UTF-8, but it isn't compatible with UTF-8.

        +
        Parameters:

        dst - destination for encoded bytes
        dstOffset - offset into destination array
