<pre>The file works for me now, and I checked my notes, and this file along with
some other files are in the section where I worked on the patch that I
submitted in <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - pdftops - some fonts are encoded incorrectly in level2 postscript"
href="show_bug.cgi?id=63963">https://bugs.freedesktop.org/show_bug.cgi?id=63963</a>
I don't remember exactly what happened, but I think that this file generated
the spaces around the bullets by using a 0 size character high up in the font
and showing it in a way that the show command added the space. Since the glyph
was empty, something didn't include it when building the font, and the
generated postscript got a range error trying to access it.
In my patch at
<a href="https://bugs.freedesktop.org/page.cgi?id=splinter.html&bug=63963&attachment=128294">https://bugs.freedesktop.org/page.cgi?id=splinter.html&bug=63963&attachment=128294</a>
the sequence below in PSOutputDev.cc is what stops the range check while
preserving the spacing. For the glyph used for spacing, code > maxGlyph (which
is no loss because the glyph is empty and 0 size) but dx > 0 and needs to be
counted.

5179 } else if (maxGlyph > 0 && code > maxGlyph) {
5180 // Ignore this code.
5181 // Using it will exceed the number of glyphs in the font and
generate
5182 // /rangecheck in --xyshow--
5183 if (nChars > 0) {
5184 dxdy[2 * (nChars-1) ] += dx;
5185 dxdy[2 * (nChars-1) + 1 ] += dy;
