blank after submitting any form

I see no error in the error log...

Ok.. some more insight.

1. Looking at the .module file in WordPad, I see some strange characters:
t('Show user 粑mage if available and no image uploaded for this team').'?');

2. I don't know any php, but is it ok that the following line has a ;) inside a t() ?

$form['help_text'] = array('#type' => 'markup', '#title' => t('Help'), '#value' => t('Please give at least width or height of the images
in the team table! Remember it should be a table, so the layout should be human viewable! ;)<br /><br />'));

3. If i edit the file in NotePad i don't see that strange text, but if i open it with WordPad i can see it. When I delete it, it says that the file will lose all formatting (which is a good thing right?). After deleting those chars and deleting the cute smiley (just to be safe), i get the following error after enabling the module:
Parse error: syntax error, unexpected T_CONCAT_EQUAL in /home/.../sites/all/modules/og_teampage/og_teampage.module on line 252
