Can’t match to Japanese word

Thank you for the great plugin.
However, when I specify a Japanese word as Replace Keyword in Replacements, it is not converted.
I checked the code and found that

class-url-shortener-public.php

$pattern = '#(?! <. *?) (\b'.preg_quote($keyword).' \b)(?! [^<>]*? >)#si';

If this \b is present, the Japanese will not match. If remove it, it will match.　I modified the code as follows and it is working fine.

if ( strlen( $keyword ) != mb_strlen( $keyword, 'utf8' ) ) {
	// have multibyte language
	$pattern = '#(?!<.*?)(' . preg_quote( $keyword ) . ')(?![^<>]*?>)#si';
} else {
	// have not multibyte language
	$pattern = '#(?!<.*?)(\b' . preg_quote( $keyword ) . '\b)(?![^<>]*?>)#si';
}

Thanks.
