Win32 GUI accent not displayed even in UNICODE - c++

Question

I'm making a GUI using window API with MSVC 2022,
When I try to display é char in my widget, there is a problem with encoding
That is the code for the widget:
I tried with wide string and the TEXT macro
CreateWindowW(
L"STATIC", // Predefined class; Unicode assumed
L"éééé", // text
WS_VISIBLE | WS_CHILD, // Styles
10, // x position
10, // y position
250, // Button width
50, // Button height
hWnd, // Parent window
NULL, // No menu.
hInst,
NULL); // Pointer not needed.
CreateWindowW(
L"BUTTON", // Predefined class; Unicode assumed
TEXT("réééé"), // Button text
WS_TABSTOP | WS_VISIBLE | WS_CHILD | BS_DEFPUSHBUTTON, // Styles
300, // x position
10, // y position
250, // Button width
50, // Button height
hWnd, // Parent window
(HMENU)ID_OK, // No menu.
hInst,
NULL); // Pointer not needed.
My MSVC use UNICODE for the file (I checked in parameters) and defines UNICODE and _UNICODE.
Did I miss something ?
Thank you for your time
Thank to John is the comment, I solved the problem, the cpp file was saved in utf-8 instead of utf-16. This can be changed with the 'Save as' menu.

Yes, the charset used in MVSC doesn't need to be the same than the one used in the library you are using, or the one selected at runtime. Check your library documentation, to support UNICODE, as it seems to be showing your unicode sequences as iso-latin-1 character pairs.
IMHO Microsoft has taken long to adapt to unicode. Despite MVSC already supports it, it is very probable that the Windows environment/library you use is not supporting it (or configured to) by default. The comment you use in the CreateWindowW call is not enough to make it to assume UNICODE characters. You'll probably need to specify it somewhere else.
