in reply to Re: utf8 output with 5.8
in thread utf8 output with 5.8

to answer myself: it depends on the LANG environment 
[rose@localhost rose]$ export LANG=C    
[rose@localhost rose]$ perl -e 'print "\x{f6}"' | od -tx1
0000000 f6
0000001
[rose@localhost rose]$ perl -e 'print pack "U", 0xf6 ' | od -tx1
0000000 f6
0000001

[rose@localhost rose]$ export LANG=de_DE.UTF-8
[rose@localhost rose]$ perl -e 'print pack "U", 0xf6 ' | od -tx1
0000000 c3 b6
0000002
[rose@localhost rose]$ perl -e 'print "\x{f6}"' | od -tx1
0000000 c3 b6
0000002
