I encountered the same issue than joe dot bowman at edigitalresearch.com
Even if i read on the web that it is a usual issue when using PHP 5.6 and upper, i didn't encounter it on every sites on which i use PHP 5.6.
Nevertheless, i had to find a solution because, when the issue appears, it's embarrassing. This is what i found thanks to Alexandra López on http://hasibul.info.
Instead of :
if (function_exists(‘iconv’))
{
// These are settings that can be set inside code
iconv_set_encoding(“internal_encoding”, “UTF-8?);
iconv_set_encoding(“input_encoding”, “UTF-8?);
iconv_set_encoding(“output_encoding”, “UTF-8?);
}
i use :
if (PHP_VERSION_ID < 50600) {
iconv_set_encoding('input_encoding', 'UTF-8');
iconv_set_encoding('output_encoding', 'UTF-8');
iconv_set_encoding('internal_encoding', 'UTF-8');
} else {
ini_set('default_charset', 'UTF-8');
}

As of PHP 5.6, this throws a Deprecated level error, as is consistent with setting the iconv.*_encoding ini settings:
iconv_set_encoding('internal_encoding', 'UTF-8');
triggers:
PHP Deprecated: iconv_set_encoding(): Use of iconv.internal_encoding is deprecated in ...

On PHP 5.2.5 when iconv.*_encoding values are set using php_admin_value in the Apache configuration file, this call will fail and return false.
