The Opus format specifications requires that tags are encoded in UTF-8, so that's the only encoding
opustags supports. If your system encoding is different, the tags are automatically converted to and
from your system locale. When you edit an Opus file whose tags contains characters unsupported by
your system encoding, the original UTF-8 values will be preserved for the tags you don't explicitly
modify.
