[Exim] Problem with address rewriting

Hi,

Many thanks to Phil for exim 4.14,

especially for adding better support for header rewriting with the "w" flag.
But here I found a strange little problem with my rewriting rules.
The simplest version reproducing the problem, will all
database lookups removed, is this:

####     REWRITE CONFIGURATION
*@* "harry <$1@???>" fw
*@*  harry@??? f

this produces invalid from-headers:

$exim-4.14-1 -C exim.test  -brw hellmund
  sender: hellmund@???
    from: harry <hharry@???

(It works when RFC2047 encoding is involved:
*@* "härry <$1@???>" fw
*@* harry@??? f

produces:

    from: =?iso-8859-1?Q?h=E4rry?= <harry@???>
)
