Interpolation doesn't happen after data is stored in the string, so the problem is likely in the data retrieval and/or transport stage. That is to say that no matter what crud you have in $string, high-ASCII, control codes, or otherwise, print doesn't really do anything fancy (binmode aside, which controls the application of CR-LF conversions in DOS/Windows).

Specifically: 
    my $var = "\\what will I get?.";
    print $var;

    \what will I get?.

That will return the "interpolated" version. 
    my $var = '\\\\what will I get?.';
    print $var;

    \\what will I get?.

That will print whatever you give it. Of course, you can always take the other way around and get some truly safe string data: 
    my $var = quotemeta("\\what will I get?.");
    print $var;

    \\what\ will\ I\ get\?\.

I don't think CGI does anything fancy with backslashes, so are you sure the data gets in there in the right format? As Graham pointed out, using quotemeta on your input data may help out.
