Can't compile when path contains special character "é"

I have put a project folder in a folder named Téléchargements (Downloads).
While compiling the project, I receive this error :

/software/libraries/Qt/Qt5.5.1/5.5/gcc_64/bin/uic /home/theshadowx/Téléchargements/QSanguosha-master/src/dialog/cardoverview.ui -o ui_cardoverview.h
File '/home/theshadowx/T??l??chargements/QSanguosha-master/src/dialog/cardoverview.ui' is not valid
make: *** [ui_cardoverview.h] Error 1

As you may notice the path has changed from Téléchargements to T??l??chargements

However this error is not shown when the path to the project doesn't contain special characters
