I suggest just to be sure you walk along each character to find the difference. Something like this:
# there are probably better ways of doing a string diff...
my ($s1, $s2) = ($title_checking, $titlenamefromindex);
for (my $i = 0; i < length( $s1); $i++) {
print "Different at $i\n" if (substr( $s1, $i, 1) ne substr( $s2, $
+i, 1);
}
(You may need to make minor fixes to above)
If you spot any bugs in my solutions, it's because I've deliberately left them in as an exercise for the reader! :-)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
