Fix playing of video files with Chinese names

The old implementation was using QUrl::toEncoded in order to retrieve a
filename from a URL, but it uses toLatin1 internally which substitutes
all non-ASCII characters with question marks that leads to ill formed
path. The new implementation uses QUrl::toString with a subsequent call
to QString::toUtf8 and it basically leads to the same results while
preserving non-ASCII characters.
