Seeing warnings like
Wide character (U+434) in substitution (s///) at /usr/local/lib/x86_64-linux-gnu/perl/5.22.1/Template/Filters.pm line 62
Perldiag tells:
====
Wide character in %s
(S utf8) Perl met a wide character (>255) when it wasn't expecting one. This warning is by default on for I/O (like print). The easiest way to quiet this warning is simply to add the :utf8 layer to the output, e.g. binmode STDOUT, ':utf8' . Another way to turn off the warning is to add no warnings 'utf8'; but that is often closer to cheating. In general, you are supposed to explicitly mark the filehandle with an encoding, see open and binmode.
====
If I remove 'use locale' from T::F, warning gone.
So why is it there and how to use it with unicode strings?
