<b>Betreff:</b> HTML entities</div>
<div name="quoted-content">Is the list of HTML entities fixed, or is there a mechanism through which new<br/>
ones can be requested? I think the right group to contact is the W3C, or is it<br/>
IETF?<br/>
<br/>
For example, I think "²³&sup4;" should expand to "²³⁴" and not to<br/>
"²³&sup4;" as it currently does.<br/>

Best,<br/>
