Find file names with invalid encoding on Linux

I have files copied from Windows computers in ancient times. The filenames contain special characters and they have been messed up somewhere along the way. For example I got a file named 9.5.2 Modelo de aceptaci??n (espa??ol).doc in the folder 9 Garant??a del Estado.
