[themes] Is this a Bug?

[袁韬韬]

Simply a little test:
1,create a new theme folder "testfoo".
2,create a page.tpl.php which has a content:
<?php
    print $content;
?>
3,create a node.tpl.php which has a content:
<?php
    print $title;
    print $content;
?>

Ok, now enable the theme, you will found there is a strange character
before the every title except the first one.

Is this a bug?
Thank you !
