Description:
I am using a Microsoft Surface Laptop with an up-to-date WIndows 10 (german instal) and LibreOffice 24.2.1.2 (fresh install). 
When I create a calc file and use e.g. armenian or russian letters in the filename and then try to import some data into writer via DDE-Link, it shows "????" as the file name and only imports an empty table. It works fine for docs with latin characters as the filename. None of the folders where the doc is located in, have non-latin characters, just the filename itself.
Other than that, I can work with these files without any issue, saving, opening and so on. I can import pics into writer with non-latin characters in the filename.
A friend of mine uses MacOS and tried to replicate the issue, but it works fine for him. 

Steps to Reproduce:
1.create new calc file with eg. armenian letters in the filename
2.input some numbers and copy the cells
3.create new wirter file and try to import the copied data via DDE-Link

Actual Results:
Filename is shown as question marks and an empty table is imported.

Expected Results:
The copied data is properly imported.


Reproducible: Always
