About Chinese fonts can't be displayed normally

[nehonpa]

Can anyone tell me how to display Chinese fonts normally?

dpg.create_context()
dpg.create_viewport(title='123',decorated=True,vsync=False,width=700, height=100)

with dpg.font_registry():
    # dpg.add_font(file, 20)
    with dpg.font("D:/font_files/NotoSansSC-Bold.otf", 45, tag="secondary_font"):
        dpg.add_font_range_hint(dpg.mvFontRangeHint_Default)
        dpg.add_font_range_hint(dpg.mvFontRangeHint_Chinese_Simplified_Common)
        dpg.add_font_range(0x4e00, 0x9fa5)
    with dpg.font("D:/font_files/NotoSansSC-Bold.otf", 10, tag="thr_font"):
        dpg.add_font_range_hint(dpg.mvFontRangeHint_Default)
        dpg.add_font_range_hint(dpg.mvFontRangeHint_Chinese_Simplified_Common)
        dpg.add_font_range(0x4e00, 0x9fa5)
with dpg.window(label="中文") as window:
       dpg.bind_item_font(window, "secondary_font")


dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()
