<p>"[<i>Note</i>: Pathnames containing spaces require special handling by the user to avoid
truncation when read by the extractor. &mdash; <i>end note</i>]" sounds like a quoted manipulator
as specified in the C++14 draft in [quoted.manip] would be useful.</p>

<p>Consider using quoted manipulators for stream insertion and extraction.</p>

<p><i>[2014-02-10, Daniel suggests wording]</i></p>


<p><i>[2014-02-12 Applied LWG/SG-3 Issaquah wording tweak to use ISO doc number for reference to C++14.]</i></p>




<p id="res-2619"><b>Proposed resolution:</b></p>

<ol>
<li><p>Change 8.6.1 [path.io] as indicated:</p>

<blockquote><pre>
template &lt;class charT, class traits&gt;
basic_ostream&lt;charT, traits&gt;&amp;
operator&lt;&lt;(basic_ostream&lt;charT, traits&gt;&amp; os, const path&amp; p);
</pre>
<blockquote>
<p>
<i>Effects</i>: <code>os &lt;&lt; <ins>quoted(</ins>p.string&lt;charT, traits&gt;()<ins>)</ins></code>.
<p/>
<del>
  [<i>Note</i>: Pathnames containing spaces require special handling by the user to avoid truncation when read by the extractor.
  &mdash; <i>end note</i>]
</del>
  <p/>
  <ins>
    [<i>Note</i>: The <code>quoted</code> function is described in ISO 14882:2014 &sect;27.7.6.
    &mdash; <i>end note</i>]
  </ins>
  <p/>
<i>Returns</i>: <code>os</code>
</p>
</blockquote>
<pre>
template &lt;class charT, class traits&gt;
basic_istream&lt;charT, traits&gt;&amp;
operator&gt;&gt;(basic_istream&lt;charT, traits&gt;&amp; is, path&amp; p);
</pre>
<blockquote>
<p>
<i>Effects</i>:
</p>
<blockquote><pre>
basic_string&lt;charT, traits&gt; tmp;
is &gt;&gt; <ins>quoted(</ins>tmp<ins>)</ins>;
p = tmp;
</pre></blockquote>
