When I mass tagging my mp3s, I found mp3tag messed up my tags when I entered a Chinese character whose ASCII code contains a backslash. I then try putting the backslash into the tags in another mp3 file, and the tags of the file is messed up too. I hope the problem can be fixed very soon.
Also there is another bug in file renaming. When there is a invalid character in a tag, mp3tag will suggest another file name but the Chinese characters after the removed invalid character is messed up. I hope the problem can be fixed too. (not as critical than the previous one )
Thank you very much.
