autolink code sample
If there are link text, change tag.
Maybe the following code can use the other language.
function make_clickable($text) {
$ret = ' ' . $text;
$ret = preg_replace("#(^|[\n ])([\w]+?://[\w]+[^ \"\n\r\t<]*)#ise", "'\\1<a href=\"\\2\" >\\2</a>'", $ret);
$ret = preg_replace("#(^|[\n ])((www|ftp)\.[^ \"\t\n\r<]*)#ise", "'\\1<a href=\"http://\\2\" >\\2</a>'", $ret);
$ret = preg_replace("#(^|[\n ])([a-z0-9&\-_\.]+?)@([\w\-]+\.([\w\-\.]+\.)*[\w]+)#i", "\\1<a href=\"mailto:\\2@\\3\">\\2@\\3</a>", $ret);
$ret = substr($ret, 1);
return($ret);
}

I used to add in /wp-content/themes/MyThemeDir/function.php.
But I found out same code in /wp-includes/formatting.php around line 682.
