Dear Monks,

I have a latin-1 string that I am trying to do some substitutions on, but the substitution is not happening:


use strict;
use warnings;
use 5.010;

use Encode;

my $str = "ThĀt Āpple";  #'A with circumflex'
say $str;

my $unicode_str = decode('iso-8859-1', $str);

my $pattern = "\x{00C2}"; #unicode for 'A with circumflex'
$unicode_str =~ s/$pattern//g;

my $latin1_str = encode('iso-8859-1', $unicode_str);
say $latin1_str;

The output from the first say(), indicates there is something wrong from the very beginning. Instead of seeing an "A with circumflex", I see an "A with tilde". Then no substitution is performed, and I see the same string that is output the first time. My terminal is set to Latin-1.

If I add a use utf8 statement, then for the first say() I see "A with diaeresis(umlaut)", but then the substitutions are performed, and the second say() outputs "Tht pple". However, the utf8 docs specifically warn against using a use utf8 statement for upper Latin-1 codes, and also because I'm not using any utf8 characters in my program file, it doesn't make sense to me to include that statement.

How can I get the first say() to output a string where I see "A with circumflex", and how can I get the substitution to work as well?

Thanks
