Would that work on content that stopped mid-tag? Assuming the original
copy is:

<p>This is some sentence, with an <abbr title="Abbreviation">abbr</abbr>
in the middle of it.</p>

If I was asking for only the first 50 characters, I'd get this:

<p>This is some sentence, with an <abbr title="Abb

Would either htmltidy or htmlpurifier be able to handle that? I don't
mind whether it tries to repair the tag or remove it completely, as long
as it does something to it.
