I don’t know whether this is possible, but it would be convenient if we could say
Code:
$text=i18n::translate('Assign the default language for the site.<br /><br />When <b>%s</b> is set, users can override this setting through their browser\'s preferred language configuration, configuration options on their Account page, or through links or buttons on most <b>webtrees</b> pages.',i18n::translate('Allow user to change language'));
at help_text.php:2296 and other places like that..
