Hello Nicholas, The PDF you link to has a decent title in its metadata, but if it isn't there, i would not rely on the first N characters of the content, as it is very unreliable. You can find all kinds of bad markup right at the start of PDFs.
But there is a choice, you can still use the raw filename, which is fine in most cases, and usually prettier to read than the first N characters. Another trick is to use the most common hyperlink anchor, which is most of the times very readable and descriptive.
