This issue occurs because of changes in default installed fonts in Windows 10.


To reduce the effects of these concerns, make sure that your applications appropriately declare the recommended xml:lang attribute as per MSDN guidance. For more information about the guidance, see xml:lang Handling in XAML in MSDN and Introducing xml:lang in XAML.
