[Windows] Unicode custom text input window shows question marks when inserting an emoji

Reproducible with: 2021.3.45f1, 2022.3.54f1, 6000.0.31f1, 6000.1.0a8
Reproducible on:
Windows Standalone Player
Testing environment: Windows 10 Enterprise 21H2
Not reproducible on: Windows 11
Note:
- IsWindowUnicode() returns true for both windows
Customer notes:
- We have an idea about this strange behavior. Unity uses GetMessage and PeekMessage methods in the main window loop. Possibly, UnityPlayer.dll was built without "UNICODE" defined. In that case, ANSI versions of these methods were used (GetMessageA and PeekMessageA respectively). Instead of GetMessageW and PeekMessageW. We used DllViewer and looks like UnityPlayer.dll linked to GetMessageA and PeekMessageA version only.
