If I select a song on softsqueeze with accented characters in filename and hold the play button (to launch a MusicMagic Mix), the song title appearing in the mix gets garbled. Also, a duplicated song is created in the database. When browsing the album with the Web server, I have one entry displaying the correct title pointing to the correct filename, and one entry with a garbled title pointing to a garbled filename. Here is an example.

I am proposing the following fix in Plugins.pm. Change:

for (my $j = 0; $j < $count; $j++) {

   my $newPath = Plugins::MusicMagic::Common::convertPath($songs[$j]);
   $::d_musicmagic && msg("MusicMagic: Original $songs[$j] : New $newPath\n");
   push @mix, Slim::Utils::Misc::fileURLFromPath($newPath);
}

for:

for (my $j = 0; $j < $count; $j++) {

   my $enc = Slim::Utils::Unicode::encodingFromString($songs[$j]);
   $songs[$j] = Slim::Utils::Unicode::utf8decode_guess($songs[$j], $enc);

   my $newPath = Plugins::MusicMagic::Common::convertPath($songs[$j]);
   $::d_musicmagic && msg("MusicMagic: Original $songs[$j] : New $newPath\n");
   push @mix, Slim::Utils::Misc::fileURLFromPath($newPath);
}

The two lines I added are basically replicating the fix to bug 3318 that was implemented in Importers.pm when importing data from MusicIP, only here it is applied to mix generation.
