Problems with special characters using lv_textarea_add_text(ta, "á")

The function lv_textarea_add_text(ta, "á") doesn't display special characters in the text area. What could be the issue?

I tried using the function lv_textarea_add_text(ta, "á") to add the text "á" to the text area. I expected the text area to display the character "á" correctly. However, the special character did not display as expected.

The character you are trying to display in not within the ASCII range. To add special character/symbol (Unicode), you need to add font to your project by using any of below methods:

  1. Go to lvgl online font converter and upload a font that supports Unicode characters. Make sure to specify the correct Unicode range (e.g. Latin Extended-A) when converting the font.
  2. By using offline font converter available in directory lvgl/scripts/

Apply added font using: lv_obj_set_style_text_font(ta, &ADDED_FONT, LV_PART_MAIN | LV_STATE_DEFAULT);

Note: The above API is valid for lvgl version 9.0.0. A similar API is available in other versions, also maybe with different API name.
