The problem is that some files do this as an obfuscation technique.

What might be detected is fonts that don't have unicode extraction. See 
in LegacyPDFStreamEngine "if (unicode == null)". Make your own or extend 
it and check for TextPosition objects with unicode null. (See 
PrintTextLocations example from the source code download on how to get 
TextPosition objects).
