I thought to have seen somewhere that since something like 5.16 use utf8 wad the default.
from your other post
do you want to tell that for each operation in perl, and particularly for IO, I MUST specify utf8?
Is there today another coding than utf8?
Yes, but utf-8 surely would be a more useful default.
Is not it possible to specify that all is utf8 (unless exceptions) at computer level ? or at least at perl level, or at least at script level ?
will be suitable for you.
