What have you tried so far?

According to documents

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*You code here*/
```c
lv_obj_t * scr = lv_disp_get_scr_act(NULL); 
    static lv_style_t style1;
    lv_style_copy(&style1, &lv_style_plain);
    style1.text.font = &kaiti16;
    lv_obj_t * label1 =  lv_label_create(scr, NULL);
     lv_label_set_style(label1, LV_LABEL_STYLE_MAIN, &style1);
    lv_label_set_text(label1, "测试");
    lv_obj_align(label1, NULL, LV_ALIGN_CENTER, 0, 0);

## Screenshot and/or video
If possible, add screenshots and/or videos about the current state.

My first guess would be the font for whatever reason does not have the symbols you are writing? Double check the Unicode character values in the text above have a corresponding value in the font.

What if anything does it show?

thank you,I changed the IDE encoding format to UTF-8,I can successfully display
