"Unicode tagging issues"?

i'm reading http://wiki.musicbrainz.org/VirtualDuplicateRelease
if a release has a track with a pi symbol in it's title than the release needs to be entered into MB twice? (once for the symbol, and once as a translation that read "pi")
i can sort of understand entering a new release for a translation, but an entire additional release for track title unicode (which picard can correct via prefs > encodings) seems a bit much.
if the track is titled Π than it's titled Π

with Picard 0.7.0 is "Unicode tagging" really an issue at all?
