Hi Tony,
first of all sorry for misdirecting my first answer. I didn't mean to
steer you away from the list.
The issue is a misunderstanding of the ascii package, it seems. It is
a package for typesetting special ascii symbols. That's why it uses a
special encoding and has glyphs only in specific positions of that
encoding. In particular, you cannot use it as a textfont in T1. The
doc tells you to either use the commands which it supplies, or use the
glyph number as in \textascii{\char"16}. So:
\documentclass{article}
\usepackage{ascii}
\begin{document}
\SO
\end{document}
(when run through pdflatex) produces a PDF which uses the ascii font
for the musical score (plus the standard text font for the page number
which I did not turn off).
from pyx import *
text.set(cls=text.LatexRunner)
text.preamble(r"\usepackage{ascii}")
c = canvas.canvas()
c.text(0,0,r"\SO")
c.writePDFfile("test.pdf")
(when run through python) produces that same symbol. If your PyX is
quite new you'll get a warning to follow the switch from runner to
engine, which does not matter for the font issue.
Cheers
Michael
