So i have found the ultimate solution, not the perfection but near the perfection! :)
I write French without accent! And all works fine!
As that is only for the vertical list of the Dinos Ligthings, it's not a big disaster! :)

This is for my old computer! :)

For the modern seems it's more hard to found a solution!

Another thing : what about put a new image icone button for a specific command on the CommandBar?

Ok I found a solution for the modern computer but that is some tiedous :) Before maybe a morez direct native system by Michael ? :)
No accent, and format must be in Notepad "Ansi as Utf-8" else some problems!
In Moi.ini Kill the line LightingOptions=....
And no possibility to have accent for your icon "Lighting" or other without numerous again some problems!

So this is! That was a big fight for me! :)
(in fact just 3 words must have accent in French: "Défaut", "Pétrole" and "Zèbre" so not a big deal !
