You should try using the
ord($ch) function to find out what the character is. It looks like it might be ASCII character number 1, but it's hard to tell on a webpage. If it is an unprintable ASCII character, you could use the
tr operator to delete it:
#!/usr/bin/perl
use strict;
use warnings;
my $string = "\001hello\002world\003lookit\004these\005weird\006charac
+ters";
my $string2 = $string;
# replace ASCII chars from 0 to 8 with spaces
$string =~ tr[\000-\010][ ];
# or delete weird chars:
$string2 =~ tr[\000-\010][]d;
print "string is $string\n";
print "string2 is $string2\n";
__END__
