All String values are encoded as a sequence of UTF-8 characters preceded by the length in bytes.
The length in bytes is encoded as Int32. A value of −1 is used to indicate a ‘null’ string.
Strings with embedded nulls (‘\0’) can lead to unpredictable application behaviour because embedded nulls have special meaning to some DevelopmentPlatforms. For this reason, embedded nulls are not recommended and ByteString should be used instead. That said, Encoders may encode Strings with embedded nulls. Decoders shall use the length to read all bytes in String.
Figure 4 illustrates how the multilingual string ‘水Boy’ is encoded in a byte stream.
