Hi.
I've also experienced this bug. In Spanish there are names as "Dënver" or "Último", and those characters with ´ or ¨ are often replaced by Chinese characters. It happens only under "Fiio Music" app; if I go to the folder via "File Management", those names are correctly written.
Great product.
Regards.
Yeah, it's not that much of a deal to me. But I can understand that there are people who listen to alot of bands/artists that have weird letters in their names. Can imagine those people would like a fix for it
