Description of problem: 
In Red Hat Linux 9 it doesn't seem to be possible to write a ⬠(euro) by simply typing 'Alt Gr + 
5' (which is a very common combination over here in Europe). In Red Hat Linux 8.0 that was 
possible. In both cases LANG was set to en_US.UTF-8. 
 
Version-Release number of selected component (if applicable): 
 
 
How reproducible: 
Always 
 
Steps to Reproduce: 
1. Type 'Alt Gr + 5' 
2. 
3. 
     
 
Actual Results:  No ⬠(euro) appeared, but a 5. 
 
Expected Results:  A ⬠(euro) should appear. 
 
Additional info: 
 
FWIW my workaround. To /usr/X11R6/lib/X11/xkb/symbols/us_intl I added these lines: 
     key <AE05> {   [     5,   percent      ],  
          [   EuroSign         ]   }; 
 
Besides, to  /etc/X11/XF86Config I added the line: 
   Option   "XkbOptions"   "grp:switch" 
 
I'm not sure whether this is only possible solution, whether editing /etc/X11/XF86Config was 
really necessary and whether there isn't a better way to do this, but: this worked for me!
