Ok, I'm trying to print the character called odieresis (btw I don't
know all that much about PS programming). So after some digging around
I decide that I have to create a new font with a different encoding
vector.

First of all, is this the correct way to do it?

When, I wrote a small test program that was meant to do this and I
used ghostscript to check the results... I found that ghostscript and
my HP Laserjet III and PS cartridge differed in their output for the
following code:---

%!
% PS program to demonstrate what I think is a gs bug.
%
% I wanted to output the char odieresis and therefore created a new font based
% on Times-Roman but with a new encoding vector (having all slots paint
% an odieresis).
%
% The following is a test piece of code that should do this. The new font is
% called TR-Mine.
%
% The output of the program should be
%
%     Hello$$$$$There
%
% Where Hello is larger than There and the $s are odieresis'.
%
% The Bug:
%
% If the base font for TR-Mine is the same as the font being used for text
% at the time of changing to the new font then gs does not do the change
% properly. The output I get is:
%
%     HelloabcdeThere
%
% But if I change the base font to Helvetica (e.g.) then I get the correct
% output (with Helvetica odieresis').
%
% The code works as expected on an HP Laserject 3 (with PS cartridge).
%
% Note: I may be doing something wrong as I'm only a PS newbie!

% Create a copy of Times-Roman
/Times-Roman findfont dup length dict /myfont exch def
{1 index /FID ne
  {myfont 3 1 roll put}
  {pop pop}
  ifelse
} forall

% Change the encoding to make a into odieresis.
/newencoding 256 array def
0 1 255 {newencoding exch /odieresis put} for
myfont /Encoding newencoding put

% Register changed font.
/TR-Mine myfont definefont pop

% Select normal text font.
/Times-Roman findfont 20 scalefont setfont
100 100 moveto
(Hello) show

% Use newly created font.
/TR-Mine findfont 20 scalefont setfont
(abcde) show

% And now use a different font.
/Times-Roman findfont 10 scalefont setfont
(There) show 
showpage

%----------------- End of code ---------------------------------------

Is this a known bug with gs? Is this the correct way to get hold of such
a character?

Any help or guidance would be appreciated.

Thanks,

Frank.
