Screenshot of the bug experienced with Thunar

Hello,

I am running Mageia Cauldron (kernel 5.14.10-desktop-1.mga9) with the Xfce graphical environment (xfce4-session-4.16.0-2.mga8.src.rpm) and I am experiencing a bug when I transfer files and folders to a USB Drive through Thunar (thunar-4.17.6-1.mga9.src.rpm).

The specific issue is with files and folders with French names containing special characters (é, è, ê, à, î, ô, û, etc...). When I copy or move these items from my computer to a USB drive, either through drag-and-drop or through the copy/cut-and-paste in the right-click options, the names landing in the drive are changed where every special French character become "__" (I have attached a screenshot to illustrate what I mean. If it is a folder, all the files inside with French special characters in their names end up with "__" instead of said special characters.

I played around with that issue and here are further observations:
1) The type of USB drive does not matter, the bug is the same for all of them.

2) It only happens when I copy/move from my computer to the drive. When I go from the drive to the computer, the files/folders names are not affected.

3) This only occurs when I proceed through Thunar. If I copy/move through a terminal (mv, cp, rsync), the names landing in the USB drive are not affected.

4) The source RPMs I mentioned above are the most recent ones that are running on my computer as of today, but the bug also existed with previous versions.

I will attach the details on my hardware, but here is a short summary:
