My problem is that EAC doesn't support unicode characters. When I copy and paste the Chinese characters into EAC, it just won't save it after outputting the files into Flac. Right now, my plan is to just rip the audio tracks into flac as file 1, 2, 3, and etc. Then I'll re-tag the files afterwards. However, I'm just wondering if there is a faster way to do this?

If I re-tag my Flac files later, it wouldn't re-encode the file right? Meaning I won't suffer any lost in audio quality during the process right?

Even if it did re-encode the file (which I don't think it would) this would be a lossless-to-lossless conversion so there would be no effect on quality.

The Answer is no. Re-tagging does not re-encode the file. However you may want something like audiograbber to see if it fits your needs better.
