TextInputEvent.Text encoding for different languages

Release Type: Official Release

Version: 4.1.0.1838

Platform(s): Windows

Describe the bug
When I enable text input events and try to get them, events text can get wrong encoding with some languages.
I found this bug when testing Cyrillic and Greek characters input, with English, German or Japanese it worked fine.

To Reproduce
Steps to reproduce the behavior:

1. Create a project with the TextEdit control (this is the simplest way to get and visualize input events).
2. Install any Cyrillic or Greek keyboard layout
3. Try to input something into the TextEdit with different languages and see what is displayed in the TextEdit
4. Compare it with the text typed in the Notepad or any other apps

Expected behavior
Text encoding should've been detected correctly, all languages should be encoded in the same encoding.

Additional context
I found out that I can get Cyrillic letters back with changing encoding from UTF-16 to Windows-1251. Also Greek letters can be get when changing the encoding from UTF-16 to Windows-1253. However, when changing the encoding, Japanese letters are lost.
Also, when you copy and paste the text into the game, it is handled correctly, letters are the same as copied

So what can I do to keep all languages available for input?

Start with the Windows TextInputEvent handling used by the TextEdit control and reproduce the issue with Cyrillic, Greek, English, German, and Japanese keyboard layouts. Compare the event text with Notepad and verify that UTF-16 preserves every language without language-specific encoding changes.
