The viewport title appears as garbled characters in Chinese

[s95050937]

I have currently set the viewport title to Traditional Chinese. The Chinese displayed within the window is correct. However, I've noticed that the Chinese display becomes garbled in the title bar and the name when the application is minimized. Is there any way to fix this issue?

import dearpygui.dearpygui as dpg
import dearpygui.dearpygui as dpg
dpg.create_context()

reg = dpg.add_font_registry()
fontName = dpg.add_font(file="C:\Windows\Fonts\msjh.ttc", size=18, parent=reg)
dpg.add_font_range(0x0001, 0x9FFF, parent=fontName)
dpg.bind_font(fontName)
with dpg.window():
    dpg.add_button(label='測試')
dpg.create_viewport(title="測試", width=1000, height=500)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()

A bit of explanation (from the corresponding Discord thread):

It's an issue with how DPG configures viewport title on Windows. Quite similar to tickets #1075, #2212, and ImGui ticket #5725 (but occurs in a different place in the code). Reported to ImGui repo as #5975.

Basically mvPrerender() on Win32 uses SetWindowTextA() to set window title, but it passes in a UTF8-encoded string, which is very wrong.

Until the issue is fixed, I'd recommend to use plain ASCII for the window title (yep, that restricts it to English-only text).

Can the problem be solved?

ocornut/imgui@fe0a24f
DefWindowProcW() instead of DefWindowProc() so that title text are correctly converted
Can the problem be solved?

Can the problem be solved?

Yes, in a couple of different ways. I'm not sure yet which one should be implemented. Depends on how the build process is set up.

Looking forward to you fixing this issue

Wrong font file for title drag rectangle.
