Hi,
In linux unicode input for U++ works well, but in windows i cannot input with unicode, because i use a vietnamese input soft. This soft use keyboard hook API to input vietnamese characters.
If you want to input unicode like that way you can patch some code like here:
File: Win32Wnd.cpp, Function: sProcessMSG(MSG& msg)

Old code:
Quote:

DispatchMessage(&msg);

New code:
Quote:

if(IsWindowUnicode(msg.hwnd))
	DispatchMessageW(&msg);
else
	DispatchMessage(&msg);



File: Win32Wnd.cpp, Function: sProcessMSG(MSG& msg)
Old code:
Quote:

if(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
//.... something here
}


New Code:
Quote:

bool succeed = IsWindowUnicode(msg.hwnd)==true?PeekMessageW(&msg, NULL, 0, 0, PM_REMOVE):PeekMessage(&msg, NULL, 0, 0, PM_REMOVE);
if(succeed) {
    //.... something here
}



It is like this picture:

Thanks. I am afraid the second change does not make sense (you do not know whether window is unicode when calling PeekMessage), so I have rather replaced all PeekMessage with

static bool PeekMsg(MSG& msg)
{
	if(!PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE)) return false;
	return IsWindowUnicode(msg.hwnd) ? PeekMessageW(&msg, NULL, 0, 0, PM_REMOVE)
	                                 : PeekMessage(&msg, NULL, 0, 0, PM_REMOVE);
}
