It's not uncommon for translators to accidentally drop some printf-style formatting characters from strings, particularly things like ordered parameters:

en "1$s's status on 2$s"

ja "%2$s における %1$ のステータス"

Here, the 's' string specifier got dropped by mistake. This should be fairly easy to detect: make sure we have the same number of params and that we're not missing any explicitly-numbered ones. We could highlight the suspicious parts and prompt the translator to correct it or accept anyway.

Since this particular check is applicable only to programs using printf-style formatting from their strings, it could perhaps be applied only when using gettext (which usually is paired with lots of sprintf fun)
