What's the value of characters in execution character set?
<p>Quote from C++03 2.2 Character sets:</p>

<blockquote>
  <p>"The basic execution character set and the basic execution
  wide-character set shall each contain all the members of the basic
  source character set..The values of the members of the execution
  character sets are implementation-defined, and any additional members
  are locale-specific."</p>
</blockquote>

<p>According to this, <code>'A'</code>, which belongs to the execution character set, its value is implementation-defined. So it's not 65(ASCII code of <code>'A'</code> in decimal), what?!</p>

<pre><code>// Not always 65?
printf ("%d", 'A');
</code></pre>

<p>Or I've a misunderstanding as to the <strong>value</strong> of a character in execution character set?</p>
