Invalid or incomplete multibyte or wide character

The other day I downloaded a video with JDownloader and when I tried to move it into my usb memory, the system did not recognize the file and it could not move it.

The error message which Linux returned was "Caracter multibyte amplio inválido ó incompleto" (I have configured my system in Spanish), "Invalid or incomplete multibyte or wide character" in English.

javi@javi-kubuntu:~$ mv .jdownloader/downloads/TICs_espa�olas.avi /media/disk-2/
mv: no se puede efectuar «stat» sobre «/media/disk-2/TICs_espa\244olas.avi»: Caracter multibyte amplio inválido ó incompleto

This is a serious problem, because in addition to not be able to copy or move the file, you can neither remove it.

The issue is that file is encoded with ISO-8859-15, and my system is configured as UTF-8. The solution consists in converting the file name encoding to UTF-8. In order to carry out this operation, we can use the convmv utility.

javi@javi-kubuntu:~$ sudo aptitude install convmv

javi@javi-kubuntu:~/.jdownloader/downloads$ convmv -f iso-8859-15 -t utf-8 TICs_espa�olas.avi

No changes to your files done. Use --notest to finally rename the files.

The previous output shows us the final file name after the conversion. So as to apply the changes permanently, you have to add the --notest argument.
