Hello, After further investigation, I found my problem was due to a wrong environment : the charmap was not UTF-8 : $ locale -c charmap LC_CTYPE ISO-8859-1
I've fixed this by modifying /etc/default/locale was : LANG=fr_FR Fixed with LANG=fr_FR.UTF-8 Then $ sudo update-locale $ locale -c charmap LC_CTYPE UTF-8 Bug should be closed, Mathieu
