<p>
The definitions for execution character set and execution wide-character set were reworded and moved to 
16.3.3.3.4.1 <a href="https://wg21.link/character.seq.general">[character.seq.general]</a>/p1.2 after applying CWG motion 10 "<a href="https://wg21.link/P2314R4" title=" Character sets and encodings">P2314R4</a> Character 
sets and encodings", but I can't figure out what these terms mean from the wording, which now reads:
</p>
<blockquote><p>
"The <i>execution character set</i> and the <i>execution wide-character set</i> are supersets of the 
basic literal character set (5.3 [lex.charset]). The encodings of the execution character sets and the 
sets of additional elements (if any) are locale-specific."
</p></blockquote>
<p>
Would it be possible to provide complete definitions for these and give examples of each?
</p>

<p><i>[2022-01-29; Reflector poll]</i></p>

<p>
Set priority to 3 after reflector poll.
Should say <em>something</em>, even if just "unspecified".
<a href="https://wg21.link/P1885R9" title=" Naming Text Encodings to Demystify Them">P1885R9</a> will expose the possible encoding programmatically,
so could say it's implementationd-defined and implementations can document
that you should ask <code>std::text_encoding</code>.
