Umm, sorry, my poor English might have slipped to describe what
I thought.

At present, libiconv (or iconv() in libc) is not required function
for poppler. poppler cpp wrapper requires iconv(), but other part
does not use iconv() at all. If it is acceptable to use iconv()
in other parts, it would be easy to make a hook to translate
non-Unicode legacy CJK encoding to Unicode string. Do you think
using iconv() (in poppler, out of cpp wrapper) is too huge hack?
