Special characters / other languages [terminal]

openwrt 19.07.3 putty ssh (spanish)

I was sharing a usb trough samba an 2 files did not appear in windows. In terminal the looked like this "Reuni▒n" which is "Reunión" an it has spaces in the filename, it doesn't let me select neither.

I do experience this issue, though. To remove the file, I had to type it in full, or copy/paste
