This needs to be url_length > 1 because WriteInto() says the length has to be at
least 2. It wouldn't make sense for a URL to be just the NULL terminator.

actually, i looked more and the bug is in pdfium. i'll send a different cl for
that.

Done.

       unsigned short* data =
-          reinterpret_cast<unsigned short*>(WriteInto(&url, url_length + 1));
+          reinterpret_cast<unsigned short*>(WriteInto(&url, url_length));
       FPDFLink_GetURL(links, i, data, url_length);
     }
     Link link;
