WordPress SEO by Yoast

Hello !

WordPress version: 3.3.2
WordPress SEO version: Version 1.1.9

My site is multilingual site with 5 languages.
WordPress SEO by Yoast plugin has multilingual support and languages files.
I did this:
I inserted category title template:
“%%category%% %%page%% – site_name”
and the this template should be multilingual and the words “page” and “of” should be translated.

I expected the plugin to do this:
The title to be:
“category_name Page 1 of 2 – site_name”
in all languages.

Instead it did this:
The title “category_name Page 1 of 2 – site_name” works only for English pages.

I changed the core code of the plugin in the file ‘wpseo-functions.php’
line 142:
‘%%page%%’ => ( $max_num_pages != 0 ) ? __( ‘Page’,’wordpress-seo’ ).’ ‘.$pagenum.’ ‘.__( ‘of’,’wordpress-seo’ ).’ ‘.$max_num_pages : ”,

but the words has no translations.

Can you please add translation support to this title template?

Many thanks.
