Almost solved:


function lugpa_change_subscribe_button_texts($args){

$fakeCbox = "<span class='subscribe-icon'></span>";
$args = array_merge($args, array(
'before' => '',
'subscribe'=> $fakeCbox.' Subscribe to thread notifications',
'unsubscribe'=> $fakeCbox.' Unsubscribe from thread notifications',
));
return $args;
}
// in a future please check if all these hooks subscribes to a "topic"
add_filter('bbp_before_get_forum_subscribe_link_parse_args', 'lugpa_change_subscribe_button_texts');
add_filter('bbp_before_get_topic_subscribe_link_parse_args', 'lugpa_change_subscribe_button_texts');
add_filter('bbp_before_get_user_subscribe_link_parse_args', 'lugpa_change_subscribe_button_texts');


However I’m not sure if all these hooks works over the same thing. Meaning, if they all are related to “thread subscriptions”.

One more thing: I’d like to be able to distinguish if I’m in “replys” page or in “my subscriptions” page. Because If I’m in the second one I should keep the short version.
