iTunes shows all songs as ૱ after Migration Assistant

I recently upgraded my laptop from the first unibody MacBook Pro to the new i5 MBP.  To import my old laptop, I booted in target disk mode and used Migration Assistant.

Everything worked great with the Migration Assistant, except when I launched iTunes.  All the letters in the interface appeared as squares.  When getting info on the song the title in the top of the window is correct, but all the data appears as “૱”

This issue was cleared after quitting and relaunching iTunes.
