It looks like we got problems after updating the plugins:
git client plugin 2.8.6 -> 3.0.0
git plugin 3.12.1 -> 4.2.2
 
When starting the freestyle job on the Windows agent it is not possible to clone the git repository (doesn't matter ssh or https) if the folder name in Jenkins is written in Cyrillic.
 
ERROR: Error cloning remote repo 'origin'
hudson.plugins.git.GitException: Command "git fetch --tags --progress – https://repo_url/repo.git +refs/heads/:refs/remotes/origin/" returned status code 128:

With English folder names everything goes fine.
 
On Linux agents, there are no problems with cloning repositories using Cyrillic names
 
Java arguments on windows and linux agents are same: 'Dfile.encoding = "UTF-8" -Dsun.jnu.encoding = "UTF-8"'
