How virtuemart encode special characters?

[emt_tmp]

Hello,
I have tried to add html characters to internal note field but once I check them in database they are altered.
<p> tag is saved as &#60;p&#62;

I have noticed that product_s_desc and product_desc doesn't have the same problem.
I have searched for htmlentities and htmlspecialchars functions in core files but didn't find something to disable.

Could you please guide me where do I have to search for this function?

Thank you in advance
