Try
su.EncodeUrl(namefileinrussian.jpg, "uft8")

so...
B4X:
FTP.DownloadFile(  "/hotel/"&su.EncodeUrl("выакекем.jpg", "uft8"), False, File.DirRootExternal, "test.jpg")

B4X:
        Dim r As Reflector
        r.Target = FTP1
        r.Target = r.GetField("client")
        r.SetField("_controlEncoding", "UTF8", "java.lang.String")

This code just modifies file names into:
B4X:
f.Name=preview_���� � ��� ��������.jpg
f.Name=preview_���� � ���.jpg
f.Name=preview_������� �������.jpg
f.Name=preview_������������.jpg
But this should be used before the connection, but it's impossible, we have only Init method.
So, no use.

And "OPTS UTF8 ON" command is unknown on this FTP server....

It's from TotalCommander FTP client, connected to this FTP-server - and RU names are well visible, so - support is available, but how to activate\use ?

It's logcat text from logcat, after listing:
Sub FTP1_ListCompleted (ServerPath As String, Success As Boolean, Folders() As FTPEntry, Files() As FTPEntry)

So you can see in the following post that it worked. Why do you write

"But this should be used before the connection, but it's impossible, we have only Init method.
So, no use."

???

You need to find out the encoding that your server uses and set the encoding accordingly. This encoding will be used to parse the list result.

Yes, Erel, you are right, if to set "CP1251" encoding - it's OK !
"Used before connection" - it is always mentioned in Stackoverflow about this subject, but i did not know whet moment the connection is done.

So, no universal way to detect what encoding is needed for each FTP server ? Say, if files named on various languages...
