<h3>Token not allowed in PDFDocEncoded string</h3>
<p/>The package <i>hyperref</i> produces this error when it doesn&rsquo;t
know how to make something into a &ldquo;character&rdquo; that will go into one
of its PDF entries.  For example, the (unlikely) sequence
<blockquote>
<pre>
\newcommand{\filled}[2]{%
  #1%
  \hfil
  #2%
}
\section{\filled{foo}{bar}}
</pre>
</blockquote><p>
provokes the error.  <i>Hyperref</i> goes on to tell you:
<blockquote>
<pre>
removing `\hfil' on input line ...
</pre>
</blockquote><p>
It&rsquo;s not surprising: how would <em>you</em> put the
typesetting instruction <code>\</code><code>hfil</code> into a PDF bookmark?
<p/><i>Hyperref</i> allows you to define an alternative for such
things: the command <code>\</code><code>texorpdfstring</code>, which takes two
arguments &mdash; the first is what is typeset, the second is what is put
into the bookmark.  For example, what you would probably like in this
case is just a single space in the bookmark; if so, the erroneous
example above would become:
<blockquote>
<pre>
\newcommand{\filled}[2]{%
  #1%
  \texorpdfstring{\hfil}{\space}%
  #2%
}
\section{\filled{foo}{bar}}
</pre>
</blockquote><p>
and with that definition, the example will compile succesfully
(<i>hyperref</i> knows about the macro <code>\</code><code>space</code>).
