USB stick caching oddity / acute accent character?

Ok, so I copied all purchased songs from ITunes onto a USB stick and put them in the cars USB socket.
Worked fine ... except one Artist, Emeli Sande, did not appear in the list. Nor did her album, nor her songs.
Rebooted center console. No luck. Removed stick and reinserted several times. No where to be found.
Copied her songs over again. Nothing.
Puzzled, I put stick back in my laptop, and checked permissions on each folder. They were the same.
I then looked at all artist names and tried to determine something unique about her.
Her sande, e, is actually not e, but with an acute accent. Don't know how to produce it on a USA keyboard. (Accent aigu en Francais, not that she's French ... Scottish)
So I renamed her to Sande. (Without accent.)
Popped it back in car and ... huh???
She's now in the list, playing as well as she sings ... but she shows up in the list as Sande (with the accent!)
Is this minor bug unique to the S interface or something generic to computers in general. (Even though she shows up fine on stick and in my Windows Folders.

The displayed name probably comes from somewhere other than the file/directory name which is why the accent shows up. Whether the filename works with extended ASCII character or Unicode characters is particular to each operating system. You're lucky, most of my songs just have XXX where the characters are and about half have a ? instead of an album cover, and about half of the ones that do show the album cover either have the wrong cover or they have a very tiny image inside a big white square.

Where else would it come from?
