STB to support UTF-8, it needs to be built with the `STBI_WINDOWS_UTF8` define

My Issue/Question

@v-ein reply on discord
Okay so I digged in a bit and it turns out that for STB to support UTF-8, it needs to be built with the STBI_WINDOWS_UTF8 define. I've added -DSTBI_WINDOWS_UTF8 to the build config in my local copy of DPG, and it worked - load_image can now load images with non-ASCII paths.

Definitely go ahead and open a ticket on GitHub.

To Reproduce

You can open a ticket on GitHub. I've just tried load_image on a non-ASCII path - doesn't work for me either, even though it should (it uses STB under the cover, which seems to be UTF-8 aware).

Expected behavior

viewport title will output mess code for non-ASCII characters
output_frame filename will output mess code for non-ASCII characters
load_image filename
save_image filename
file_dialog will show ????? for non-ASCII characters

will save or show non-ASCII correctly

Standalone, minimal, complete and verifiable example

import dearpygui.dearpygui as dpg
dpg.create_context()
dpg.create_viewport(tilte=non_ASCII_chars)
main_window_tag=dpg.generate_uuid()
with dpg.window(tag=main_window_tag):
	image_file_name_with_non_ASCII=non_ASCII_chars+".png" #Use filename with non-ASCII characters on windows
	print (image_file_name_with_non_ASCII)
	dpg.split_frame()
	dpg.split_frame()
	dpg.output_frame_buffer(file=image_file_name_with_non_ASCII)
	dpg.split_frame()
	dpg.split_frame()
	dpg.file_dialog() #load paths with non-ASCII characters will show ???????
	dpg.load_image(file=image_file_name_with_non_ASCII) filename cannot be non-ASCII characters
	dpg.save_image(file=image_file_name_with_non_ASCII) filename cannot be non-ASCII characters

dpg.set_primary_window(main_window_tag,True)
dpg.configure_item(main_window_tag,horizontal_scrollbar=True)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()
