XF 1.2 Error after updating to PHP 5.6


I'm running a 1.2 xenforo forum (if i remember correctly, 1.2.7) and 2 days ago my host updated the PHP version to 5.6. Since then, i'm having, at least, an error when registering:

iconv_set_encoding(): Use of iconv.internal_encoding is deprecated

I'd like to know how can i solve it without updating it (i've saw something about 1.3.6 being fixed) but i'd like to know how can i solve it, because i have a lot of 1.2 addons plus many own code and it would require a big amount of work to update it to a newer version (I'm waiting until xenforo 2.0 to even think about migrating).



Well-known member
Looks like they do a check for the PHP version now

            $origenc = PHP_VERSION_ID < 50600
                        ? iconv_get_encoding('internal_encoding')
                        : ini_get('default_charset');
            if (PHP_VERSION_ID < 50600) {
                iconv_set_encoding('internal_encoding', 'UTF-8');
            } else {
                @ini_set('default_charset', 'UTF-8');
