Many Wikimedia wikis use "header icons" to display meta information about articles - whether they have a particular quality ranking, whether they are protected or semi-protected or whatever. These are absolutely positioned using CSS.
To see a widely used example of this, check out this template on en.wp:
On right-to-left wikis like Hebrew, these are placed on the other side of the screen, obviously.
But an issue can arise if you read a right-to-left wiki with a left-to-right language set in your preferences.
- Go to Hebrew Wikipedia - http://he.wikipedia.org/ - and sign in.
- Set your preferences to have English (or another LTR language).
- Go to the article on Israel - http://he.wikipedia.org/wiki/%D7%99%D7%A9%D7%A8%D7%90%D7%9C
This article has icons for being protected (or semi-protected, can't tell: my Hebrew isn't that good) and for being a featured article. Only it overlaps the title of the article which has been put on the left.
One possible solution for this is to specify a particular CSS class or other method which positions the 'meta icons' based on where the title is.
It is worth noting also that not all articles in right-to-left languages have right-to-left article names - see http://he.wikipedia.org/wiki/London_Calling
