you have to set the right encoding in the form page, via the response 
object and/or meta tags

browsers are supposed to send form results in the encoding of the form page

i dont know if it is available prior zope 2.7, but you can specify the 
encoding when using ustring and utext in the form field names, zope then 
  automatically decodes the values and gives u a unicode.

eg: <input name="title:ustring">
