Bugzilla bug 17428 informs us that the Romanian language used to be written with the cedille. This was wrong and there have been improvements in Unicode and it is possible to write Romanian properly.
You have to use Windows Vista for this.. I wonder how Linux supports Romanian.
As many people use legacy Windows systems, a straight conversion to the proper characters is not an option at this time for the Romanian Wikipedia. The bug report talks about a conversion similar to what is done for Chinese or Serbian. A problem is that this kind of software is not part of what the Internationalisation people at translatewiki.net do.
So what to do, who to turn to?
