You could use ${rfc2047:<string>} and headers_add/remove. But even if
you did it would not help you, because there is no reliable way[1] to
identify the used charset and ${rfc2047 only supports ISO-8859-1 so
you would change e.g. "This € is a Euro-symbol" to
"=?ISO-8859-1?Q?This_=A4_is_a_Euro-symbol?=" which is not an
Euro-symbol at all but "currency sign".

I know that is a lame example but if you took
russian/chinese/UTF-8/whatever input and declared it was ISO-8859-1
you'd really make things worse.
