Difficult to Delete Files in Linux

There's a lot of stuff about this on the Internet, but most of the examples there are contrived. How does one delete files that are really stubborn? e.g.,

$ find ./ -inum 167794
./àKÈÿÿÿÿ@
$ find ./ -inum 167794 -exec rm \"{}\" \;
rm: cannot lstat `"./\037\340\025K\021\004\310\377\377\377\377@\020\002"': Invalid or incomplete multibyte or wide character
