Declaring headers for HTML emails

hey all

I am working on a form and I want to declare a html header in the process file so the user gets an email in rich text or html format

my big problem is that there is a form

 <form><option value='¿Que Tal? (078) $6.75'>¿Que Tal? (078) $6.75</option>

that uses special characters like the inverted question mark and I need it to appear in the email that the user sees when they get the email order confirmation.

So does anyone know how to do this in classic ASP?
