Java java.io.filenotfoundexception for file path with cyrillic characters

I have a file whose name contains characters not only from the plain ASCII character set, but also from a non-ASCII character set. In my case it contains Cyrillic characters.

Here's a snippet of my code:

String fileName = "/Users/dnelepov/Downloads/тест изображение.png";
File sendFile = new File(fileName);
if (sendFile.exists()) {
    // Some code
}

The code in sendFile.exists if block is not being executed.

Why isn't the file recognized?

My system configuration locale

LANG="ru_RU.UTF-8"
LC_COLLATE="ru_RU.UTF-8"
LC_CTYPE="ru_RU.UTF-8"
LC_MESSAGES="ru_RU.UTF-8"
LC_MONETARY="ru_RU.UTF-8"
LC_NUMERIC="ru_RU.UTF-8"
LC_TIME="ru_RU.UTF-8"
LC_ALL="ru_RU.UTF-8"

UPDATE

I found that this error is on JDK from Oracle.

I created project on Eclipse, and file was found. I checked project properties and found Mac OS 6 JDK.

Then I change it to JDK 7 and file was not Found again.

My problem is that I need to use JDK 7 with JavaFX. Not Mac OS version. So my problem still exists.

I've made a video to show this error Video with error

UPDATE 2

Thanks to eumust for answer, this code works:

Path path = Paths.get("/Users/dnelepov/Downloads/test/");
    Files.walkFileTree(path, new SimpleFileVisitor<Path>() {
