-  The --extrude option can produce code with syntax errors
+  The --extrude and --mangle options can produce code with syntax errors
     The --extrude tries to put as many newlines in the formatted code as
-    possible. This option is very useful for testing perltidy but not for
-    actual formatting. Occasionally it will produce code which Perl
-    considers to have a syntax error. These problems usually involve code
-    where Perl is having to guess the tokenization based on whitespace.
-    Since the --extrude option is typically only used for testing perltidy,
-    this type of error should not normally occur in practice.

+    These options are very useful for stress testing perltidy (and Perl) but
+    not so much for normal formatting. Occasionally they will produce code
+    which Perl considers to have a syntax error. These problems often
+    involve code where Perl is having to guess the tokenization based on
+    whitespace. The given/when and switch/case statements are also
+    particularly vulnerable to unusual line breaks and whitespace. This type
+    of error should not normally occur in practice, but if it does it should
+    be easy to fix the problem by rerunning perltidy with more normal
+    parameters or by manually changing whitespace or newlines.
+
+  The Pod:Html module has some bugs
+    For the most part Pod::Html works very well and is very convenient
+    because it part of the standard Perl distribution. But for example the
+    following line
+
+      =item B<< <Deck> = Session->new_cflt_deck; >>
+
+    which uses double brackets to contain single brackets does not render
+    correctly.
+
+  Perltidy does not handle UTF-8 encoded files
+  Two iterations are sometimes needed
+    Usually the code produced by perltidy on the first pass does not change
+    if it is run again, but sometimes a second pass will produce some small
+    additional change. This mainly happens if a major style change is made,
+    particularly when perltidy is untangling complex ternary statements. Use
+    the iteration parameter -it=2 if it is important that the results be
+    unchanged on subsequent passes, but note that this doubles the run time.
