"Unequip empty item slots", => Déséquiper les slots vides
"Show equipment condition", => Afficher l'état de l'équipement
"Show weapon charge", => Afficher la charge de l'arme
"Mark sets in tooltips and inventory", => Marquer le set dans le menu et l'inventaire
"Show quality and condition", => Afficher la qualité et l'état

at worse, replace "les" conditions by "la" condition. (but it rarely used with this meaning)

conditions in french only means "if... else" not the repair status : "état" is more clear.

i have the special character table somewhere if needed.


Edit, i forgot that tooltip shouldn't be translated by menu : "Mark sets in tooltips and inventory", => Marquer le set dans les tooltips et l'inventaire -- although the real word for tooltip would be "infobulle", but it's not very relevant for a square window full of information.
or maybe something like "la fiche info". idk if there is an official french term in game for it.
