Multilanguage Support

To permit the string translation on my multi-language blog I have added the macro function __() in file gcll.php at line 132

….
131: $limit = $this->opt(‘upper_limit’);
132: $available = __($this->opt(‘characters_available’));
133: $boxsize = strlen(strval($limit));
134: $out = <<<EOT
….

My multi-language plug-in was WPML. I have not found other ways.
This little change is correct for you or there are others (better) solutions?
Tnanks 🙂
