 # Description 说明
-Use 16384 Chinene characters as the alphabet, like the 64 chars in the base64.<br/>
-使用16384个汉字作为字符表，就像base64用64个字符作为字符表一样。
+Use 16384 Chinene characters (\u4E00 to \u8DFF) as the alphabet, like the 64 chars in the base64.<br/>
+使用16384个汉字作为字符表，就像base64用64个字符作为字符表一样。<br/>
+We use \u3E3E as a sign of << 16, and \3D3D << 14.<br/>
+另外，使用\u3E3E作为解码时文件末尾向左偏移16位标识(对应编码时加0对齐2字节)，使用\3D3D作为解码时文件末尾向左偏移14位标识，对应编码时未满8字节的偏移量。
 
 # Benefits 优点
-Save more space and since the code 0x0000 is encoded to "一", finding zero space seems to bo easier.<br/>
