Are you sure the file has the images attached the official way? Can
you run metaflac --list on the file and post the results? It should
have a block of type "6 (PICTURE)" in it.

There are two reasons:

 1. In order to keep backward compatibility, we had to keep
non-Windows as char*. Windows was not supported by TagLib before we
had this change, so we could change the ABI for Windows, but not for
other platforms.

 2. Filenames on other UNIX based OSes (with the exception of OS X)
are byte strings, which don't necessarily need to have to be encoded
in a particular Unicode encoding. If you would send a wchar_t* string
to TagLib, it would have to somehow figure out how to convert it to
char*. This would be just guess work based on the current locale or
something like that. This is best done in the application code, not in
TagLib.
