That has nothing to do with the notebook being very old.  That's just a 
stupid bug in how InputForm communications between kernel and FE happen. 
 We already had an open bug report about this, and I just pinged the bug 
again with a reference to your post.  Here's a way you could work around 
the bug:

Block[{$CharacterEncoding = "Unicode"}, Print[\[Mu]//InputForm]]
