Unreadable Greek filenames

[J-ohn]

What happened:

1. Mounted a share with files whose names contain greek characters (tried both with a vm running windows as the smb server and an azure files storage as the smb server)
2. Attached to the pod and did an ls on the share
3. The file names had question marks instead of the greek characters e.g. ????? ??.JPG
   What you expected to happen:
   Comparing to the behavior of the azureFile csi driver and running the same test the files listed using ls in linux we got file names like so ''$'\317\203\317\207\316\265\316\264\316\271\316\277'''$'\317\207\317\211\317\201\316\271\317\202'''$'\317\204\316\271\317\204\316\273\316\277''_-_2022-03-12t100557_115.png' which in turn are interpreted correctly by the application. If you create a file with greek characters from the application under the mounted folder, the file is correctly shown with ls (with escaped characters like the above) and listed by the application, but if you visit either the windows server or azure storage and see how it shows the filename you get something like this ��εδιο���ι�_�ι�λο-_2022-03-12t100557_115.png
   How to reproduce it:
4. attach to a running pod with a mount on it
5. cd to your mounted directory
6. touch ''$'\317\203\317\207\316\265\316\264\316\271\316\277'''$'\317\207\317\211\317\201\316\271\317\202'''$'\317\204\316\271\317\204\316\273\316\277''.png'
7. visit the mount from the storage's side (azure storage explorer for example), instead of seeing a file name like so "σχεδιο_χωρις_τιτλο.png" you will see an ineligible file name
