Sorry for the delay.

Unicode characters without the nls option in bash-4.3.46 are still a 
problem.

config.log seems to find iconv declaration fine, but it doesn't test for 
the actual library, see the log below. HAVE_ICONV is undefined. I think 
it comes from AM_GNU_GETTEXT.

The problem is that bash shouldn't even have an optional HAVE_ICONV. 
Since Unicode characters are the major feature, you iconv presence 
should be an unconditional requirement.
You probably need to use AM_ICONV and fail when it isn't present.

Please fix this bug.
