Hi,

edit: apologies but the utf8 characters are not displaying properly in code. Each string is ϗblah頁.

I am having an issue in understanding what is happening between the two code snippets below. The first example generates a wide character error as expected since I haven't set STDOUT's encoding to utf8. However, in the second example, although I have pointed STDERR at STDOUT, no such error is generated on warn and it successfully prints out the utf8 characters. What exactly is happening here?

example 1

use strict;
use warnings FATAL => qw#all#;
use utf8;

#print qq#content-type: text/plain; charset=UTF-8\n\n#;

print q#print: ϗblah頁#; # wide char error.

example 2

use strict;
use warnings FATAL => qw#all#;
use utf8;

*STDERR = *STDOUT;

#print qq#content-type: text/plain; charset=UTF-8\n\n#;

warn q#warn: ϗblah頁#; # no error.
print q#print: ϗblah頁#; # wide char error still.

Thanks,
