I'd rather not include all of glyphlist.txt in the fontconfig library,
especially as each glyph adds a relocation to the library. Restructuring
that data to avoid relocations would help, but I'm not sure I can see
the need for all of those glyph names to be provided by the library.

Is the urw symbol clone including a character which is not in the zapf
character map and is in the larger map? Does Adobe publish a smaller map
that includes all of the needed symbol glyphs and yet avoids the plain
characters? Does the urw clone offer a Unicode map that can be used to
look up the needed glyphs?

It doesn't need to be any longer -- the only use of this constant is in
relation to the built-in list of glyph names, so names longer than this
will never be useful.
