因为只有应用程序知道最适合进行分割的位置，所以显然需要在应用程序和编码模块之间进行协商，才能将输出分割成适当的大小。
Obviously, the chunking of output into appropriate sizes is a matter of negotiation between the application and the encoding module, as only the application knows the most appropriate place to break.
还有一个功能，成块传输编码，对于在预先无法知道整批大小的地方建立成批消息尤其方便。
One feature, the chunked transfer encoding, is especially convenient in the construction of batches of messages where the size of the entire batch is not known a priori.
但即使用utf - 8编码CJK XML，实际的大小可能也比utf - 16小。
But even when you're encoding CJK XML in UTF-8, the actual size gain compared to UTF-16 probably isn't so large.
