Directory Windows/System32/Config/ not visible at Win10H2

[spooch99]

This seems to be a problem with characters of the ownership names, see below!

Mounting a (generated from german/deutsch ISO) Win10 Partition with mount -t ntfs3 .. results in a nonexistent Config-directory in Windows-dir. The System was built in a qemu environment, 64bit.
The system was modified with
powercfg /H off

before shutting down. The mount command was
mount -t ntfs3 -o offset=$[512*104448],showmeta,no_acs_rules,nls=utf8 /dev/gu/win10unattend /mnt

Mounting with -o ntfs-3g results in an existing Config/ Dir.
Furthermore, looking at the dir wir "ls", the config-dir ist visible, but not accessible:

root@p51:/mnt/Windows/System32# ls -lh | grep -i config
ls: Zugriff auf 'de' nicht möglich: Datei oder Verzeichnis nicht gefunden
ls: Zugriff auf 'config' nicht möglich: Datei oder Verzeichnis nicht gefunden
...
-rwxr-xr-x 2 root root 146K Dez 7 2019 AppManagementConfiguration.dll
d????????? ? ? ? ? ? config
-rwxr-xr-x 2 root root 686K Nov 19 03:49 configmanager2.dll
..

Trying the same with the englisch-international version of win10 seems running fine! The difference is imho the names of the ownership, i.e. the owner of ther config/ dir is "AUTORITÄT/SYSTEM" (with the special character "Ä"), in english the same file has the ownership "AUTHORITY/SYSTEM" (with no special character).
Imho this is a hot candidate for the problem.
