Re: search and replace these unique characters

I'm not sure what those characters are, but when I am trying to identify unusual characters, I use the ord function:

#!/usr/bin/env perl
 
use warnings;
use strict;
my $str = 'abcde';
for (split //, $str) {
    print "$_:", ord $_, ":\n";
}

Once you identify the characters, it will be easier to figure out a way of eliminating them.

Somehow, character code point numbers are always easier for me to grok (and look up on code charts) when shown in hex; also, it can help to put in a "safe" placeholder for the non-printable ones -- otherwise, they can sometimes make the display somewhat confusing: `for (split //, $str) { printf( "%s: %02x\n", (/[[:print:]]/) ? $_:".", ord()); }` [download]	[reply] [d/l]
