My cloud sync can not use more 128 symbols length of path for cyrillic codepage

Hi! It is detected a problem with WD MY CLOUD device(current firmware v04.04.04-101) and WD Sync(v.1.3.5949). When i tried to sync files i saw errors. It seems that is impossible sync files to cloud device with lenth of path to file more than 128 symbols for cyrilic codepage(CP-1251(Russian language), see screenshot.

How probably to fix this problem?
1)I see that current encoding of WD MY CLOUD is ANSI_X3.4-1968(locale charmap)
Maybe it can update current encoding to ANSI X3.4-1986 or ANSI INCITS 4-1986 for more compatibility?
2)Maybe it is possible to change codepage to UTF-8?
Select supported charsets “dpkg-reconfigure locales” and then “export LANG=en_US.UTF-8” to .bashrc
or othe way?
3)I think that some file managers software as Total Commander, Far manager or windows robocopy, Long Path Tool and others successfully decided this problem.
You can see in msdn Maximum Path Length Limitation section
“To specify an extended-length path, use the “\?” prefix”
4)Also it is possible to make symbolic link to part of path:
mklink /d c:\link “\mycloud\folder1\folder2…folder8”
and if we will copy file to c:\link it will be correctly path.
