You need to use postsubs instead of subs to ensure it's done after the
highlighter has executed (subs is an alias for presubs), but that still
won't fix it because Attribute Entry values are substituted for special
characters (see 'Attribute Entries'
(http://asciidoc.org/userguide.html#X18)).
Neither will putting pass:[🐄] in the listing because, again, the
highlighter will escape the ampersand.
The only way I can think of to ensure the ampersand is not escaped is to
use a replacement e.g.
:replacements.COW: 🐄
[source,javascript]
[presubs="none"]
[postsubs="replacements"]
----
var str = 'COW';
