Hey Vladimir, it seems the smart links doesn't work with cyrilic letters… How much it will cost to modify that for me?
You did a great tool!
Cool 10x!

Hi there. I found out the problem with cyrilics. The problem is in the regular expression matching the keywords.

The problem is here:

$reg = $options['casesens'] ? '/(?!(?:[^<\[]+[>\]]|[^>\]]+<\/a>))\b($name)\b/msU' : '/(?!(?:[^<\[]+[>\]]|[^>\]]+<\/a>))($name)\b/imsU';

The \b matches at a position that is called a "word boundary". It is not designed to work with cyrilics, so you may replace the row with:

$reg = $options['casesens'] ? '/(?!(?:[^<\[]+[>\]]|[^>\]]+<\/a>)[^a-zA-Zа-яА-Я0-9_])($name)([^a-zA-Zа-яА-Я0-9_])/msU' : '/(?!(?:[^<\[]+[>\]]|[^>\]]+<\/a>)[^a-zA-Zа-яА-Я0-9_])($name)([^a-zA-Zа-яА-Я0-9_])/imsU';

You also need to change this row:

$replace="<a title=\"$1\" href=\"$url\">$1</a>";

$replace="<a title=\"$1\" href=\"$url\">$1</a>$2";
