How to reproduce:
1. Open the attached project
2. Make sure that scripting backend is set to .NET 4.x
3. On Android device go to settings and set Region/Language/Locale to French
4. Build and run to an Android device
5. Click on "Press Me!" button

Expected result: the button text changes to '4,5' (notice the comma)
Actual result: the button text changes to '4.5' (notice the full stop)

Reproduced with: 2017.4.0f1, 2018.4.1f2, 2019.3.0a5

* works as expected on:
- Standalone (Mac, Linux, Windows) all versions
- iOS devices from 2018.3.12f1 (result on 2018.3.11f1 is '4.5' meaning no culture-variance)
