Remove spanish accent from file name

Hello All
hope all fine,

I have a question about spanish accents...
I have in a redhat server, a lot of files with � or � accent into the NAME of the file.
So my question is: Is it possible to change this name but with a script...to change all the occurence in one shot.

Exemple:

 
cd /home/
ls
espa�a1.txt
espa�a2.txt
espa�a3.txt
ch�mica.txt

The result should be:

 
espana1.txt
espana2.txt
espana3.txt
chimica.txt

Is it possible?
maybe a sed into a bucle?
Thanks a lot in advance

for f in `ls -1`; do
    tmp_f=`echo $f | tr "����" "NUin"`
    if [ "$tmp_f" != "$f" ]; then
        mv $f $tmp_f
        echo "$f is renamed to $tmp_f"
    fi
done

Note: the code is not tested.

Hi
thanks a lot for the script, tomorrow I'll send the result.
Have a nice day.
Cheers
