iconv_set_encoding deprecated in PHP 5.6.0

[fisharebest]

In PHP 5.6.0, I have not set a value for iconv.xxxxx_encoding in php.ini. php -i shows:

Directive => Local Value => Master Value
iconv.input_encoding => no value => no value
iconv.internal_encoding => no value => no value
iconv.output_encoding => no value => no value

If no value is set, then the value of ini_get('default_charset') is used.
See http://php.net/manual/en/migration56.deprecated.php

But if I attempt to get the values, I get utf-8 (lower case).

$ php -r "echo iconv_get_encoding('input_encoding');"
utf-8

As a result the function initConv() sees that utf-8 is not equal to UTF-8, and attempts to set the value. This causes a PHP_DEPRECATED error.
