 For doing I/O it is suggested that you use the autotranslating features
 of PerlIO, see L<perluniintro>.
 
+Since version 5.8 Perl uses the new PerlIO I/O library.  This enables
+you to use different encodings per IO channel.  For example you may use
+
+    use Encode;
+    open($f, ">:encoding(ascii)", "test.ascii");
+    print $f "Hello World!\n";
+    open($f, ">:encoding(cp37)", "test.ebcdic");
+    print $f "Hello World!\n";
+    open($f, ">:encoding(latin1)", "test.latin1");
+    print $f "Hello World!\n";
+    open($f, ">:encoding(utf8)", "test.utf8");
+    print $f "Hello World!\n";
+
+to get two files containing "Hello World!\n" in ASCII, CP 37 EBCDIC,
+ISO 8859-1 (Latin-1) (in this example identical to ASCII) respective
+UTF-EBCDIC (in this example identical to normal EBCDIC).  See the
+documentation of Encode::PerlIO for details.
+
+As the PerlIO layer uses raw IO (bytes) internally, all this totally
+ignores things like the type of your filesystem (ASCII or EBCDIC).
