So i downloaded these files from Bulgaria. They are the english version of the demo files for a programming tutorial. I noticed that when i try to rename the folders, each keystroke results in Russian(?) characters instead of Latin.
When i open notepad, i get the normal Latin characters. How to fix this?
It also occasionally happens in text editor programs (Notepad++, Visual Studio, Arduino IDE) but the above problem is persistent.
Notes:
I only have English and Japanese language packs installed.
Just recently scanned my Windows installation with the latest Avast (free) virus definition.
Region and Langauge > Administrative
and tell me what the non-Unicode system locale is set to. Did you check to see that you do not have any Cyrillic keyboards in your input languages list?
