I got Hangul working after adding another declaration for ISO-10646
with a :script parameter:

;; 'hangul script has a :language restriction for iso10646-1, but also
;; needs :script restriction as alternative.
(set-fontset-font "fontset-default" 'hangul
                  (font-spec :registry "iso10646-1" :script 'hangul) nil 
'prepend)

It looks like any time we have an :otf or a :language declaration for
a script, we need a :script declaration as a backup for safety.
