Strings are definitely *allowed* as glyph 'characters', so you don't
need to escape spaces.  I'm just hoping I can avoid *requiring* them
in the common case.

But that may not be worthwhile.  This isn't something that'll be typed
often anyway - if an author defines a new list-style, it will be once
per stylesheet at the most.  More likely, it'll be once per project or
once per site, or less if they make a modular sheet containing the
list-styles they like to use.  Putting in an extra few dozen quote
marks is somewhat annoying, but not a big deal in this case.
