Fixing WordPress Excerpts Word Count in Chinese

Some users reported that the WordPress excerpts word count is incorrect in Chinese. This PHP snippet should help:

function dez_filter_chinese_excerpt( $output ) {
global $post;
//check if its chinese character input
$chinese_output = preg_match_all("/p{Han}+/u", $post->post_content, $matches);
if($chinese_output) {
$output = sprintf( '%1$s

%3$s

',
mb_substr( $output, 0, 50 ) . '...',
get_permalink(),
__( 'Read more', 'generatepress' )
);
}
return $output;
}
add_filter( 'get_the_excerpt', 'dez_filter_chinese_excerpt' );
