eliminate special character in subject

Hi,

I have a recipe, which eliminates two or more "Re:", and just leaving 
one. Now I´ve got a message like this:

Subject: Re:   Re: blablabla
         ^^^^^^
         and here is the problem. If I edit the message, I can see in
         the header the special character " " (hexadecimal =A0). How can
         I delete this char by the help of a procmail recipe?

I use the following "Re:"-recipe:

:0 fhw
* ^Subject:.*Re:
 | sed -e 's/Re:[ _]\?\(Re:[ _]\?\)*/Re: /g'

TIA,
Thomas
