<p><b>Discussion:</b></p>
<p>The text of <code>codecvt::do_max_length</code>'s &quot;Returns&quot;
clause (22.2.1.5.2, paragraph 11) is garbled. It has unbalanced
parentheses and a spurious <b>n</b>.</p>


<p id="res-74"><b>Proposed resolution:</b></p>
<p>Replace 28.3.4.2.5.3 <a href="https://wg21.link/locale.codecvt.virtuals">[locale.codecvt.virtuals]</a> paragraph 11 with the
following:</p>

<blockquote><p>
  <b>Returns</b>: The maximum value that
  <code>do_length(state, from, from_end, 1)</code> can return for any
  valid range <code>[from, from_end)</code> and <code>stateT</code> value
  <code>state</code>. The specialization <code>codecvt&lt;char, char,
  mbstate_t&gt;::do_max_length()</code> returns 1.
</p></blockquote>
