Invoice pdf plugin - problem with product name

-- url of the page with the problem -- : local
-- HikaShop version -- : 2.3.2
-- Joomla version -- : 3.3.2
-- PHP version -- : 5.5.11

Hi all,
A weird thing happens with my pdf invoices when products have multiple characteristics.
Please have a look at the screenshot attached.
It looks like a <br> tag is hiding somewhere, causing the product name to be cut in 2 lines.
And that doesn't happen when products don't have any characteristic.
The email notification looks god too.
Any idea?
Thanks

Hi,
I actually found the problem, my mistake.
Wrong modification of product_name with characteristic_text in administrator/components/com_hikashop/classe/product.php
Sorry...
