I encountered a problem with unicode letter which is broken on Facebook page. It cannot read letter “ć” but instead of that it reads something like " c’ ". I tried everything (from resetting Font Cache to the SFC /scannow).
How can I solve this problem without reinstalling Windows? I upgraded Windows 10 version 1909 (18363.476) to 20H2 (19042.508), then I installed KB4579311 (19042.572).
