UTF8 problem, typo, bug

Hi,

My error_log is getting filled with these errors:

[29-Jan-2019 16:05:16 UTC] PHP Warning: html_entity_decode(): charsetUTF-8;’ not supported, assuming utf-8 in /home/ladylen/public_html/blog/wp-includes/formatting.php on line 5125

In line 5125 is:

foreach ( $emoji as $emojum ) {
if ( version_compare( phpversion(), ‘5.4’, ‘<‘ ) ) {
$emoji_char = html_entity_decode( $emojum, ENT_COMPAT, ‘UTF-8’ );
} else {
$emoji_char = html_entity_decode( $emojum );
}
if ( false !== strpos( $content, $emoji_char ) ) {
$content = preg_replace( “/$emoji_char/”, $emojum, $content );
}
}

But I think should be opposite:

foreach ( $emoji as $emojum ) {
if ( version_compare( phpversion(), ‘5.4’, ‘<‘ ) ) {
$emoji_char = html_entity_decode( $emojum );
} else {
$emoji_char = html_entity_decode( $emojum, ENT_COMPAT, ‘UTF-8’ );
}
if ( false !== strpos( $content, $emoji_char ) ) {
$content = preg_replace( “/$emoji_char/”, $emojum, $content );
}
}
;`

Or simply ‘<‘ should be ‘>’

Please check.
