Or normalize and then pack, and store only normalized strings...

However, the only actual problems people see with Unicode and normalization 
is that if someone actually does it (e.g. Apple in its file system).  This 
changes the file names in an unexpected way, and taking Unicode files to a 
Mac and then back to Linux results in garbled file names.  One of the 
problems is that there are actually 4 different normalization forms...
