-B<efa> returns zero although it didn't work properly (i.e. displays an empty
-result).
+Zero if everything went well (or at least if B<efa> thinks so), one if you
+gave ambiguous input and need to re-run B<efa> with different arguments. 255

 =head1 BUGS AND LIMITATIONS
 
-The Unicode handling is slightly messed up. Therefore, arguments to B<efa>
-should always be plain ASCII (ue instead of E<uuml> etc).
+B<efa> cannot handle Unicode in its arguments, so use plain ASCII.
+
+The Parser is quite new and may not yet cover all corner cases, use with
+caution.
