Okay, this is crazy. Now I can't reproduce it myself either: I just repeated the procedure and date parsing works as expected. The only difference with my last email is that I upgraded and rebooted my system (there was a kernel update for 4.0.4 on Arch... Among other things). I guess that would have reset my keyboard layout, but I swear I tested it multiple times over a few days before posting here.

Anyway, thanks for your insight I would have never figured this myself. I'll be wary of silent unicode character substitution :)

Just for the record:
$ localectl
   System Locale: LANG=fr_FR.UTF8
       VC Keymap: fr
      X11 Layout: fr
     X11 Variant: oss

And I am using the default monospace font in gnome-terminal and gedit. Pretty basic stuff, really.

Thanks again, Bastien
