当然在Xshell8中显示钩子函数打印的内容是不会出现乱码的，就是在RT-Thread中内部打开终端显示内容会出现问题，不知道什么原因，求大佬help

```c
#include <rtthread.h>
#define DBG_TAG "main"
#define DBG_LVL DBG_LOG
#include <rtdbg.h>

rt_thread_t th1_ptr = NULL;
struct rt_thread th2;
rt_uint8_t th2_stack[512];

void th1_entry(void *parameter) {
    while (1) {
        rt_kprintf("th1_entry running......\n");
        rt_thread_mdelay(1000);
    }
}
void th2_entry(void *parameter) {
    int i = 0;
    for (i = 0; i < 5; i++) {
        rt_kprintf("th2_entry running......\n");
        rt_thread_mdelay(1000);
    }
}
void scheduler_hook(struct rt_thread *from, struct rt_thread *to) {
    rt_kprintf("from: %s --> to: %s \n", from->name, to->name);
	//rt_kprintf("from: %.8s --> to: %.8s \n", from->name, to->name);//这个不会出现乱码
}

int main(void) {
    rt_scheduler_sethook(scheduler_hook);

th1_ptr = rt_thread_create("th1_demo", th1_entry, NULL, 1024, 1, 5);

if (th1_ptr == NULL) {
        LOG_E("rt_thread_create failed: no memory!\n");
        return -RT_ENOMEM;
    }

LOG_D("rt_thread_create success!\n");

int ret = rt_thread_init(&th2, "th2_demo", th2_entry, NULL,
                          th2_stack, sizeof(th2_stack), 3, 5);

if (ret != RT_EOK) {
        LOG_E("rt_thread_init failed: %d\n", ret);
        return ret;
    }

LOG_D("rt_thread_init success!\n");

rt_thread_startup(&th2);
    rt_thread_startup(th1_ptr);

return RT_EOK;
}
```
