It looks to me that the code that is trying to search for another font
is using the next font regexp in the list for the script, rather than
the next font that was returned in the previous list.  As you can see
from the log, all the regexps for kana are returning either the same
list of fonts, or an empty list. So the result of this searching is that
the BatangChe font gets tried over and over again.
