I could want all sorts of things.
I'm simply pointing out there's no reason why perl can't implement -C by
the time it reads line 1 of the program script. That is not "too late" as
its message would otherwise indicate. My demonstration using binmode
already shows that.
Why can't perl just call binmode itself on STDIN/STDOUT/STDERR by the
time it gets that far, instead of throwing a wobbly and telling me to do
it myself. That doesn't sound very DWIM to me....
And furthermore, binmode / decode_utf8 only get us round the IOE / A
flags respectively. There is, to my knowledge, no perl code that can set
the default UTF-8ness of new filehandles, the way that -Cio does.
And all of this presumes that whoever calls binmode knows how to test the
environment properly. It's come to my attention that this might be more
accurate:
binmode STDOUT, ":utf8" if grep m/utf-?8/i, @ENV{qw(LANG LC_MESSAGES LC_ALL)};
And even then I'm not sure it's right. Which really just proves my
point...
The -C...L flag _already_ implements the correct logic. It's just not
useful as it is...
