Thread:Project:Support desk/Problem export - import page with picture having a naming with accent character

I have a mediawiki on one server and now I want to import all the content to a new server so I export the database and the images directory to import them into the new installation in the new server

I have a problem with all the images files that have a naming with french caracter like "é" "è"....

When i look at the import from the database page Image:xxxx the image is not displayed because in the image directory it has a name with another character which replace the "é"

 here is an exemple of my page visualisation 



and when I clic on the link I have the following message



and here is the image directory aspect



How to solve this problem ? to replace all charactere into the image directory ? It is a long job ?
