special character on Filename.. help!!!urgent

I'm trying to rename a file name but the original file has a special character caused by typo. I've tried numerous combination of characters but the file name (original) is still not being recognized which in turn, would not allow me to rename the file.

Can someone help? The filename is a Oracle 9i Database Datafile.

ls -il  # get inode num of the file
find . -type f -inum "inode num goes here" -exec mv {} newfilename \;  # rename file using inum obtained from ls -il
