|Do you know where your variables are?|
Thank you, Alexander! It was widening, but did not answered to my most important questions. You answered like i suppress unicode to everyone and to everywhere. That's not my goal.
I'd like to have a sandbox in Perl, where unicode were treated naturally.
Trying make it more clear. I am not familiar with Perl history so good, but let me make assumption, that in some phase there was no strict-pragma. OK? Then someone thought, it may be good idea and found ways to implement it. Did that break any earlier code? I don't think so. But it made available widely use strict pragma.
So i am talking now. As far as i see, for module authors is there no possibility to see, do the module caller uses utf8 or not. Am i correct? And, does it break any earlier code, if they would have such a possibility? That would be a single step, IMHO :)
What operating system can currently provide perl with a complete Unicode environment (%ENV, @ARGV, STDIN, STDOUT, STDERR, open, opendir, mkdir, rmdir, unlink, ...)?
I have not deeply investigated, how unicode-proof is Linux for now, but on system level i have'nt any complains already years (Debian and Kubuntu). If you could me give some hints, how determine unicode use, i'd like to test it.
