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]]

pasting that output into an Input cell reproduces that garbage. The
problem seems to occur only with that filter, which unfortunately I use
a lot for inlining code.
