Use the generated icon font file to display white space. How to make it display icons

What have you tried so far?

I want to know if there is a problem with the file I generated

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:

    LV_FONT_CUSTOM_DECLARE(lv_a);
    #define LV_MY_AAA  "\xee\xa4\x80"


    lv_obj_t * btn1=lv_btn_create(lv_scr_act());
    lv_obj_align(btn1,LV_ALIGN_CENTER,0,-10);
    lv_obj_t * lable1=lv_label_create(btn1);
    lv_obj_center(lable1);
    lv_label_set_text(lable1,LV_MY_AAA);
    lv_obj_set_style_text_font(lable1,&lv_font_montserrat_42,0);
    lv_obj_set_style_text_color(lable1,lv_palette_main(LV_PALETTE_BLUE),0);
    lv_obj_set_style_bg_opa(btn1,0,0);
    lv_obj_set_style_shadow_opa(btn1,0,0);

Instead of

you should set your font like this:

  lv_obj_set_style_text_font(lable1,&lv_a,0);
