Libreoffice from home-manager fails to open files with greek filenames

I stumble on a strange bug.

I use nix and home-manager on debian for a long time now.
Recently, I replaced the native debian libreoffice suit with the one from home-manager.

When I try to open a file like προσκληση.docx either form command line or a running instance of libreoffice writer, I got the error:

The operation on /home/path/to/file/προσκληση.docx was started with an invalid parameter.

And the file fail to load.
If I rename the file to prosklhsh.docx everything works as expected.

This Is the first time I had a similar problem. I have different other program from home-manager opening other files with greek file names without a problem.

I assume, I am missing some specific configuration option…
Can someone enlighten me?

Thanks!
