What is the encoding for JSON:API operators? I'm trying to filter JSON:API results based on the &quot;greater than&quot; operator (&gt;).
The filtering documentation lists the operators:
\Drupal\jsonapi\Query\EntityCondition::$allowedOperators = [
  '=', '&lt;&gt;',
  '&gt;', '&gt;=', '&lt;', '&lt;=',
  'STARTS_WITH', 'CONTAINS', 'ENDS_WITH',
  'IN', 'NOT IN',
  'BETWEEN', 'NOT BETWEEN',
  'IS NULL', 'IS NOT NULL',
];

But it also notes that the symbol operators need to be encoded:
&amp;filter[a-label][condition][operator]=%3D  &lt;- encoded &quot;=&quot; symbol

Which &quot;encoding&quot; is this referring to? What is the encoding for the other operators (&gt;, &gt;=, etc.)?  How do I look them up?
Thanks to Hudri, here's the list:

= %3D
&lt;&gt; %3C%3E
&gt; %3E
&gt;= %3E%3D
&lt; %3C
&lt;= %3C%3D
