Error in MySQL query when you try to make friends with DokuWiki and Wordpress

Try to make friends with DokuWiki and Wordpress in this guide: thedeadone.net/download/getting-dokuwiki-to-use-wordpress-authentication/

At the stage of creating extra fields MySQL complains at invalid syntax.

CREATE TABLE `wp_dw_groups` (`gid` int(10) UNSIGNED NOT NULL AUTO_INCREMENT,`name` varchar(50) NOT NULL DEFAULT ”,PRIMARY KEY (`gid`),UNIQUE KEY `name` (`name`)) TYPE = MYISAM;

This query causes the error "#1064 — You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'â€":

CREATE TABLE `wp_dw_usergroup` (`uid` int(10) UNSIGNED NOT NULL DEFAULT '0',`gid` int(10) UNSIGNED NOT NULL DEFAULT '0',PRIMARY KEY (`uid`,`gid`)) TYPE = MYISAM;

And this — to "#1064 — You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '’0€2,`gid` int(10) UNSIGNED NOT NULL DEFAULT ’0€2,PRIMARY KEY (`uid`,`gid` at line 1".

Not familiar with MySQL. Where error is not present. Tell me, please.
