Last week, I faced same error on FreeBSD10.0 with solr index setup.
This is a FreeBSD10 specific problem due to iconv library (in libc).
So, solution is install the converters/libiconv package and
recompile dovecot package.
Edit mail/dovecot2/Makefile,
from
  USES=   cpe iconv libtool
to
  USES=   cpe iconv:translit libtool

Hope this helps you.
