for this sort of use can't be found.

Remove description of mechanism for disabling styling on individual
spans and blocks, users can do this themselves without us documenting
the use of a codepoint that's not specifically for this purpose.

On rare occasions styling hints may conflict with the contents of a message.
For example, if the user sends the emoji "&gt; _ &lt;" it would be
interpreted as a block quote.
Senders may indicate to the receiver that a particular message SHOULD NOT be
styled by adding an empty &lt;unstyled&gt; element qualified by the
"urn:xmpp:styling:0" namespace.

<section2 topic='Individual Directives'>
<p>
To remove styling without removing the styling directives, a whitespace
character can be inserted after the opening styling directive and before
the closing styling directive (if applicable).
This whitespace character SHOULD be U+2060 WORD JOINER to prevent line
breaks between the character that was misinterpreted as a styling
directive and the text that it would otherwise style.

<section2 topic='Entire Messages'>
<p>
An entire message may also have styling disabled to remove the need to
parse the message for styling in the first place.
Senders may indicate to the receiver that a particular message SHOULD NOT
be styled by adding an empty &lt;unstyled&gt; element qualified by the
"urn:xmpp:styling:0" namespace.

<message>

For example, the string "*emphasis*" would be rendered as
"<strong>*emphasis*</strong>".

<p>
This specification does not provide a mechanism for removing styling from
individual spans or blocks within a styled message.
Implementations are free to implement their own workarounds, for example by
inserting Unicode non-printable characters to invalidate styling directives,
but no specific technique is known to be widely supported.
