个别APP全部native后，使用APP时个别操作会异常闪退 如出现如下错误，apk下载地址：https://wwi.lanzoui.com/irqGTpi3fja

修复了，你试试，应该没问题了。

因为原来的 ZZ_ACTION_PACKED_0 = "\10\0\1\1\1\2\2\3\1\2\4\3\1\4\2\1";第二个字符为\0,如果按utf-8处理会被认为字符串被终止了, 需要使用modified utf-8 把\0用0xc0和0x80代替，而且NewStringUTF也是接收modified utf8的。

用原apk测试下，发现引起其他问题了，我再去找下原因

测试了一下，除了速度变慢了一拍，应该没啥大问题了
