I'll just address this quickly -- you lost everything after the double quote because you inadvertently screwed up how the browser reads the attribute values of the HTML. PerlMonks uses forms to collect input and send it back to the user. A well-coded text-box would look something like:

<input type="text" name="title" value="some title">
[download]

So the problem is, you've now tried to submit something like:

<input type="text" name="title" value="why does "keys reverse %hash"">
[download]

Obviously, whatever system PerlMonks is using on the backend barfs on the multiple double-quotes and just parses up to what it believes to be the closing quote.

I'd imagine there's some good reason they can't perform a regexp and substitute a double quote out -- maybe they haven't had time, or maybe there's some other reason of which we are unaware.

Regardless:

"
[download]

(that's &-q-u-o-t-;) should work in titles.

That, and other valuable pieces of info can be found at:
