What are the hard-to-escape cases? I can only see that 'url()' causes
problems, no? If we separate out images, I'm not sure we need

As John pointed out, they are really characters so the 'glyphs'
property should be renamed.

Then there's my concern about 'type' being too generic (Many other
places in CSS would also like to describe types. Should they be
allowed to use it too? If not, why should it be allowed here?)

We can address all these concerns with a syntax like this:

 @counter-style lower-norwegian-glyphs {
   alphabetic: a b c d e f g h i j k l m n o p q r s t u v w x y z æ ø å;

 @counter-style lower-norwegian-images {
   images: url(a.svg) url(b.svg) url(c.svg); /* etc */

 @counter-style cjk-decimal {
   numeric: \3007 \4E00 \4E8C \4E09 \56DB \4E94 \516D \4E03 \516B \4E5D;

 @counter-style diamond {
   repeating: ◆;

 @counter-style diamond {
   non-repeating: ⓪ ① ② ③ ④ ⑤ ⑥ ⑦ ⑧ ⑨ ⑩ ⑪ ⑫ ⑬ ⑭ ⑮ ⑯ ⑰ ⑱ ⑲ ⑳;
   start-from: 0;

(We'd need some rules to determine the winner if more than one is set:

 @counter-style foo {
   alphabetic: a b c d e f g h i j k l m n o p q r s t u v w x y z æ ø å;
   images: url(a.svg) url(b.svg) url(c.svg);
   numeric: \3007 \4E00 \4E8C \4E09 \56DB \4E94 \516D \4E03 \516B \4E5D;

but that's simple enough, we just establish relative strength between
the various types.)
