the problem seems to be in the FileManagerHistory and in the function readHistDir(). it uses "ls" to lists the history dir while the "ls" command could not recognize unicode file name (if system locale does not support that unicode chars)

Fortunately the lfs.dir() does not rely on system locale(that's what the FileChooser uses to list directory files and it works well). so the fix is to change the readHistDir to below:

for f in lfs.dir("./history") do
    local filemode = lfs.attributes(f, "mode")

    if filemode ~= "directory" then -- we can't use filemode == "file" here, when it should be "file" it is actually nil, weird
    table.insert(re, {
        dir = DocSettings:getPathFromHistory(f),
        name = DocSettings:getNameFromHistory(f),
    })
    end
end
