Installing a non-standard encoding vector

[Idris Samawi Hamid <ishamid@lamar.colostate.edu>]

Dear gang,

I'm trying to install an expert font a with a non-standard encoding vector; 
can't use texnansi, ec, etc.. I tried the following:

1. I created an encoding file for my font (minion-o.enc), following the syntax

/encminiono[
/ornament1
:
/ornament23
/space 
] def

2. I placed the encoding file in /texmf-fonts/fonts/enc/dvips/minion-o;

3. I ran TeXFont:

======================================================
       encoding vector : minion-o
           vendor name : adobe
           source path : .
       font collection : minion-o
       texmf font root : c:\context\tex\texmf-fonts
       pdftex map file : minion-o-adobe-minion-o.map
           source path : .
      processing files : all on afm path
    locating afm files : using pattern *
         copying files : afm
               copying : pmnrp8a.afm
         copying files : pfb
               copying : pmnrp8a.pfb
        no map file at : 
c:\CONTEXT\tex\texmf-fonts/fonts/map/pdftex/context/min
ion-o-adobe-minion-o.map

       font identifier : Minion-Ornaments -> text -> tfm + vf
generating raw tfm/vpl : minion-o-raw-pmnrp8a (from pmnrp8a)
! tokens 3 to 257 in encoding must be literal names
] def

 ^
     generating new vf : minion-o-pmnrp8a (from minion-o-raw-pmnrp8a)
     updating map file : minion-o-adobe-minion-o.map
======================================================

but \showfont does not show any of my characters.

There appears to be one error:

======================================================
! tokens 3 to 257 in encoding must be literal names
======================================================

The label says:

======================================================
name: minion-o-pmnrp8a encoding: minion-o mapping: minion-o handling: default
======================================================

What am I missing here? How can I can install this font with my own encoding 
so that \showfont will display it?

I enclose the complete encoding vector.

Best and Thnx
Idris
