Files with special characters not displayed

Hello,

At first I thought that my drive was corrupted because a huge folder named "Música" wasn't being listed on my mac but still showed up in windows. Then I remembered to rename it to "Musica" and now it shows. Inside this I have several mp3 tracks with special characters on its filename and none of these are listed.

I am using the trial but apparently I won't be buying it because this will just not do. Is there something I'm missing?

Please advise.

Update: Hum... I have just installed the trial for Tuxera and the same thing happens. I'm now confused. Am I doing something wrong? The drive has always worked fine. Any help is welcome.

Regards,
Nuno
