Font substitutions

[Doug Asherman]

Using Lilypond 2.2.1:

I've created some TeX fonts out of TTF fonts. I'm using the font bcor8a; 
in my lilypond file, I have the lines:

      \override LyricText #'font-name = #"bcor8a"
      \override LyricText #'font-magnification = #1.5

The font is fine in the dvi file, but turns up as courier (which it 
isn't) in the ps and pdf files. I've even run each step separately, 
specifying a map file at the dvips stage. Still, I get a courier font.

The problem isn't limited to this font; when I specify an Arial font, I 
get a Helvetica font in the ps and pdf files.

I have no problem using these fonts in a standard LaTeX document; so I 
have to think that there is some step I'm missing in either writing or 
creating the lilypond source.

Any help appreciated.
