Important: Never do a calculation inside the
sprintf()
function! The following won’t work:As explained by @sergeybiryukov here, here, here and here, this functions should NOT be use in one item or more than one item scenarios, but for singular form and plural forms, which is not the same thing. Also both strings should have placeholders.
As he stated:
This problem is also covered in Codex.
Although it would be possible address this issue changing the plural form for Russian and other slavic languages it would bring a too big effort as explained here.
Example from /wp-admin/edit-comments.php without the use of a text domain for translation.
