Currently we have the following custom strings. As more languages are added this could grow exponentially.

<string name="selected_russian_ends_in_1">выбрана</string>
<string name="selected_russian_ends_in_2">выбраны</string>
<string name="selected_russian_everything_else">выбрано</string>
<string name="bookmarks_deleted_russian_ends_in_1">закладка удалена</string>
<string name="bookmarks_deleted_russian_ends_in_2">закладки удалены</string>
<string name="bookmarks_deleted_russian_everything_else">акладок удалено</string>

It might be possible to remove the need for these by reworking the text from `___ Selected` to `Selected: __` and from `__ Bookmarks Deleted` to `Bookmarks Deleted: ___`.
