I understand how to remove carriage returns from the ends of strings -- but I'm running into an issue in a Perl script of mine where a carriage return is found before the string.
For example, my script searches for strings which start with an exclamation mark, but a line that causes problems in my script is: ^C!
Is there any way to remove this?

you could use a regexpr to clean that characters:
$line =~ s/^[^!]//;

^C
is not the cat -v
representation of carriage return, but of ETX, maybe that's the source of your confusion. s/\cC//
will remove it.
Check with Devel::Peek::Dump from within Perl or uniquote from outside for other invisible characters.
