Is there a way to replace line breaks regardless of their style (Windows CR+LF, Unix LF)? Would this regular expression replace work:
$regexp(%unsyncedlyrics%,(\r\n|\n),♪)
Oh and, by the way, how can I also delete the language identifier used in MP3 lyrics ("xxx||") when exporting? (I'm using the exported file as a tag backup, so they might end up being imported to FLAC or other formats in the future.)
