Hmm... I see what you want.
First of all, use QStorageInfo.
Second, QStorageInfo has the same problem that you're asking about. I tries to
guess filesystem labels by looking up the symlink in /dev/disks/by-label that
points to the device in question, but it has no decoding function:
if (fileInfo.isSymLink() && fileInfo.symLinkTarget() == devicePath)
return fileInfo.fileName();
There's no function to decode this in QString or QByteArray for that matter.
This has nothing to do with fromUtf8().
The decoding has to be done manually.
