In the UEFI Shell I create a file with
FS0:\> echo привет_мир.текст > привет_мир.текст
FS0:\> ls
Directory of: FS0:\
00/00/0000 00:00 38 привет_мир.текст
The U-Boot console shows it correctly:
=> ls scsi 0:1
38 привет_мир.текст
Now in Linux I mount the volume. ls shows an incorrect filename:
> ls /mnt
'пÑ'$'\302\200''ивеÑ'$'\302\202''_миÑ'$'\302\200''.Ñ'$'\302\202''екÑ'$'\302\201''Ñ'$'\302\202'
Now in Linux I create a file
# echo привет_мир.текст > /mnt/привет_мир.текст
U-Boot shows the file name incorrectly
=> ls scsi 0:1
31 ?@825B_<8@.B5:AB
So U-Boot seems not to convert file names correctly to UTF-16 before saving.
Best regards
Heinrich

No conversion from/to UTF-16 takes place at a long file name
entry in the current FAT file system.
If we implement this, it will end up with incompatibility
of (meta) data with existing media.
