Back In Stock Notifications

[nagelkruid]

Hello,
I was having problem with special chars in title and the display in the bisn form at the bottom of the page. As my shop is in utf8 it shows the ?

Now i recently noticed that replacing htmlentities in tpl_product_info_display.php solves the problem like so:

$intro_text = sprintf(BACK_IN_STOCK_NOTIFICATION_TEXT_FORM_INTRO,
    //htmlentities($products_name));
    strip_tags($products_name)); 

Is it known that htmlentities doesn't cope well with utf8?
Are there drawbacks i should consider changing the code like this?

thanks,
jeroen
