bug#893: incorrect font chosen

[Dan Nicolaescu]

Emacs still uses the wrong font in some cases.

First do:

xrdb /dev/null

Then:

emacs -Q -xrm 'emacs.Font: 
-b&h-lucidatypewriter-medium-r-normal-sans-12-120-75-75-m-70-iso10646-1'

uses the lucidatypewriter font for the default face, but doing:

emacs -Q -xrm 'Emacs.Font: 
-b&h-lucidatypewriter-medium-r-normal-sans-12-120-75-75-m-70-iso10646-1'

uses:
    x:-adobe-courier-medium-r-normal--12-120-75-75-m-70-iso8859-1 (#x20)

This used to work fine before the unicode-2 merge.
