This release is a X.X.1 fix for 1.2.0.
Before the plugin analyses post content using DOMDocument, mb_convert_encoding() was used to ensure post content HTML is property encoded (HTML entities, UTF-8).
However, use of "HTML-ENTITIES" with mb_convert_encoding() was deprecated in PHP 8.2.
PHP Deprecated: mb_convert_encoding(): Handling HTML entities via mbstring is deprecated; use htmlspecialchars, htmlentities, or mb_encode_numericentity/mb_decode_numericentity instead in ...
This workaround switches three instances of mb_convert_encoding() to htmlentities().
