[monkeycc]

import dearpygui.dearpygui as dpg

dpg.create_context()
dpg.create_viewport(title='我是中文', width=600, height=200)
dpg.setup_dearpygui()



with dpg.font_registry():
    with dpg.font(r"D:\0SDXX\DearPyGui\MiSans-Medium.ttf", 20) as default_font:
        dpg.add_font_range_hint(dpg.mvFontRangeHint_Chinese_Full)
dpg.bind_font(default_font) # Binds the font globally


with dpg.window(label="我是中国文字"):
    dpg.add_text("你好, 世界")

dpg.show_viewport()

# below replaces, start_dearpygui()
while dpg.is_dearpygui_running():
    # insert here any code you would like to run in the render loop
    # you can manually stop by using stop_dearpygui()
    print("this will run every frame")
    dpg.render_dearpygui_frame()

dpg.destroy_context()

The author probably does not convert unicode python str to wide char in the underlying windowing managment

If you realy need that, you may try to modify the source (for Windows) as shown below. It is a dirty solution without knowledge of all consequences but it is working for me. Maybe the correct fix should modify also the CreateWindow() call in the mvShowViewport(). I do not know.

src\platform\Windows\mvViewport.cpp:

#include <locale>
#include <codecvt>
#include "mvWindowsSpecifics.h"
...
std::wstring convert_to_wstring(const std::string& str)
{
	std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>, wchar_t> conv;
	return conv.from_bytes(str);
}
...
mv_internal void
mvPrerender(mvViewport& viewport)
{
...
	if (viewport.titleDirty)
	{
		SetWindowTextW(viewportData->handle, convert_to_wstring(viewport.title).c_str());
		viewport.titleDirty = false;
	}
...
}

Workaround provided and possibly a duplicate. Closing the issue.

Hi, Why is this not included in the release? For me this is also a problem. And I have seen the same issues arise for other languages. Solution not actual for current 1.9.1/1.9.2 version
