Re: Issue of formatting columns of data

[choroba]

You need to

1. Save the source file as UTF-8.
2. Tell Perl that it is UTF-8.
3. Tell Perl to encode the output as UTF-8.

#! /usr/bin/perl
use warnings;
use strict;
use utf8;
use open IO => ':encoding(UTF-8)', ':std';

print sprintf ("%-6s", "°C").   "|\n";
print sprintf ("%-6s", "Deg C")."|\n";

Output (in a UTF-8 terminal):

°C    |
Deg C |

Any of these would work:
• binmode STDOUT, "encoding(UTF-8)"
• binmode STDOUT, ":utf8"
• use open qw(:std :utf8);
• perl -C your_script

[Tux]

• *please* do NOT promote binmode ..., ":utf8";, as that is unsafe
• The :encoding(utf-8)" is missing a :
• perl -C is for output only (I'd use -COE for clarity), not for the source code. UTF-8 in source code requires perl -COE -Mutf8 -wE'say "°C"'
