请大虾们解释一下这是啥意思？
这是从网上偶尔看到的一个程序员写的情书，我看不懂字符串啥意思，请解释一下这是啥字符，为什么能输出汉语？char str[] ="3BVPSq4xF.K?=u#,"
"G'K<MrDnRr7gH%#,"
"XKf<f%G`w^=?C<#,"
"HgU_AnNR?*PDQU#,"
"1HRmK+7IO2O`Rd#,"
"A,V&M,Jw>!;6P@#,"
"3AScBdQcN41HDc!#";
int i, len;
len = strlen(str);
for (i = 0; i < len; ++i) {
printf("%c", str[i] | 0x80);
if ((i + 1) % 16 == 0)
putchar('\n');
}
putchar('\n');
for (i = 0; i < 7; i++)
printf("%c%c", str[i * 18] | 0x80, str[i * 18 + 1] | 0x80);
putchar('\n');
