Did this happend to anyone else?
Is that a limitation of the destination filesystem?
There’s an Arabic name in the bottom right. Likely the software getting confused.
Maybe the target filesystem doesn’t support those filenames. I think I saw that either with NTFS or SAMBA. Really annoying.
Can you check in a terminal? If you can see them in the terminal and not in the desktop you’re missing a font. If you can’t see them in the terminal then you’ve somehow mangled them. What was the OS and filesystems you copied from?
Are the missing ones Arabic, too? If so, there is a “noto sans Arabic” font and other symbol fonts that you’ll need to have installed. That’s really weird, though. I have Arabic everywhere and I don’t have this issue. Did you uninstall any fonts by any chance?
Yes, those are Arabic, but Chinese, Japanese and Bangla are also affected. And I have the fonts installed.
