将字符指针和字符字节声明为无符号类型的，这样可以防止8位字符的符号扩展问题。

Declare character Pointers and character bytes as unsigned to avoid sign extension problems with 8-bit characters.

在派生类中重写时，将一组字符(从指定的字符指针开始)编码为一个字节序列，并从指定的字节指针开始存储该字节序列。

When overridden in a derived class, encodes a set of characters starting at the specified character pointer into a sequence of bytes that are stored starting at the specified byte pointer.

二次出现的字符串由一个指向前一字符串的指针(以对的形式——距离和长度)代替。

The second occurrence of a string is replaced by a pointer (in the form of a pair — distance and length) to the previous string.

I'm going to delete that arrow and actually draw s2 as pointing to this chunk of memory because whereas before this sequence of chars might have lived at address 71 or whatever, well, this one might live at 91.

我不会把那个箭头删除，实际上我画了s2作为,这块内存的指针，因为,这个字符序列存储在地址71或其它的地方，这个可能存储在91的地方。
