display of utf-8 messages in exmh-2.8.0

Dear List,

	I've tried upgrading my tcl/tk in use by exmh, was :

[emile@dell540 ~]$ rpm -qa | egrep '^tcl|^tk'
tcl-8.5.13-2.fc19.i686
tk-8.5.13-2.fc19.i686
[emile@dell540 ~]$ uname -a
Linux dell540.wifi 3.9.9-302.fc19.i686.PAE #1 SMP Sat Jul 6 13:52:23 UTC 2013 i686 i686 i386 GNU/Linux
[emile@dell540 ~]$ 

	to the very latest one :

-rw-r-----  1 emile carcamo  8636908 Jul 15 13:57 tcl8.6.0-src.tar.gz
-rw-r-----  1 emile carcamo  4239836 Jul 15 13:57 tk8.6.0-src.tar.gz

	The pro's of this is fixing some folder display issue
	when any strange charset is used there. But there is a
	regression about utf-8 message contents display that
	are using a very small font instead of what worked in
	8.5.13 :

<dell540.wifi>[lib]<111>grep utf /usr/local/exmh/lib/app-defaults
*mimeCharsets: us-ascii iso-8859-1 iso-8859-8 iso-2022-jp koi8-r iso-8859-2 iso-10646-1 utf-8
*mimeUCharsets: 
*mime_utf-8_registry: iso10646
*mime_utf-8_encoding: 1
*mime_utf-8_plain_families: fixed
*mime_utf-8_fixed_families: fixed
*mime_utf-8_proportional_families: fixed
*mime_utf-8_title_families: fixed
<dell540.wifi>[lib]<112>

	Anyone has an idea on this ?? THX and with best regards.
