Handle them as normal Unicode Strings.  That's what they are.

What are you doing that's choking now?

The char after the small-a is almost certainly the combining-dieresis
accent.  See TN1150 and find "Canonical Decomposition" on that page:
  <http://developer.apple.com/technotes/tn/tn1150.html>

Or go directly to the Unicode Decomposition table:
  <http://developer.apple.com/technotes/tn/tn1150table.html>

Hard to say what you're really getting if all you're doing with it is
System.out.println().

Depending on what you intend to do with the file-name, you may have to:
  a) convert to composed-accent form.
  b) convert to UTF-8.
  c) all of the above.
  d) none of the above.
