(newstring+strlen(newstring)) = 0x00;将最后一个元素后的下一个指针内容置空 是要表示到了数组的结尾了
Json string想传递0x00-0xFF值的buff是不行的。一个简单办法是对这段buff进行base64编码,然后放到json string中,这样都是ascii字符集。

I have an issue after reading a prn file which contain this binary string "1b 41 00 1b 6d 05 00 00 00 1b 6d 01 ..." with containing "00" bytes. When I try to copy them from a byte array to a string with Append() mode. The append methode is always making from ...

此外,我发现Java在编译的时候还不会处理大于0xFFFF的Unicode字面量,所以如果你敲不出某个非BMP字符来,但是你知道它的Unicode码,得用一个比较笨的方法来让String存储它:手动计算出该字符的UTF-16编码(四字节),把前两个字节和后两个字节各作为一个Unicode数,然后赋值给String,示例代码如下所示。
