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?
Redirecting the output of ls to commands such as hexdump or od would allow to notice if the name has international characters or if they were replaced by some placeholder character (which would be represented as a repeated value across the hex dump)
