OSMC RPC movie name bad codepage

Hi!
I’m connecting OSMC to OpenHAB using RPC. Of course first I did “Now Playing: [%s]” message, but there is an issue with Movie name encoding. I’m getting this:

OSMC_Playing state updated to Китайский квартал

Also when I use ls utility on the folder where my movie files are I’m getting bad picture too:

-rw-r–r-- 1 osmc osmc 2400896977 Dec 6 23:42 Yi yi (2000).mkv
drwxr-xr-x 2 osmc osmc 4096 Dec 14 23:27 terminator antology
-rw-r–r-- 1 osmc osmc 3116822528 Dec 16 00:27 ??? (1984).avi
-rw-r–r-- 1 osmc osmc 20818271685 Dec 16 11:21 ??? ??? (1979).mkv

I must say that scrapper works perfect - I can see all movies listed above in my Movies library with actors, genres, posters etc.
I’m using Cyrillic encoding (Russian Language).

I’ve fixed filenames in console doing this:

sudo apt-get install locales-all
sudo dpkg-reconfigure locales
cat >> .bashrc < EOF

LANGUAGE=en_US.utf8
LC_ALL=en_US.utf8
LC_CTYPE=en_US.utf8
LC_COLLATE=en_US.utf8
export LANGUAGE LC_ALL LC_CTYPE LC_COLLATE
EOF

Also it looks like OpenHAB issue, because of curl works fine:

curl --header 'Content-Type: application/json' --data-binary '{ "id": 1, "jsonrpc": "2.0", "method": "Player.GetItem", "params": {"properties": ["title"], "playerid": 1}}' 'http://192.168.0.99/jsonrpc'

And I get right response:

{"id":1,"jsonrpc":"2.0","result":{"item":{"id":155,"label":"Миньоны","title":"Миньоны","type":"movie"}}}
