Please ignore - I believe the issue is in the file - apologies if anyone wasted time looking at this

I want to read a file and display it in a Tk-based editor for which I have inherited the support role. It successfully loads many files containing utf8 characters. However, when I attempt to read the file below, it fails to interpret the utf8 characters correctly. The file contains the ascii characters "ABC", a space, then two Cyrillic characters: U+0440 (Cyrillic Small Letter Er) and U+0435 (Cyrillic Small Letter Ie).

I have extracted what I believe to be the relevant bit of code, and added a printf to output the characters in hex. I would expect the following output:

41
42
43
20
440
435
a

Or possibly (looking at the utf-8 encoding for those two characters):

41
42
43
20
d1
80
d0
b5
a

[download]

I actually get the following which displays as "ABC ре" in the editor:

41
42
43
20
e0
a5
a

Any help would be gratefully received.

Code

#!/usr/bin/perl
if ( open my $fh, '<', "321t.txt" ) {
    my $line = <$fh>;
    utf8::decode($line);
    for (0..length($line)-1) {
        printf("%x\n",ord(substr($line,$_,1)));
    }
}
